iOS Introduction


iPhemeris uses the Swiss Ephemeris which is based on the Jet Propulsion Laboratories (JPL) DE431 ephemerides and the US Naval Observatory equivalent for Asteroids. It offers sub-second accuracy to with .001 seconds of arc.

If you’ve purchased the Extended Ephemeris (via In-App purchase) coverage is 7700 years (4700 BC to 2995 AD) otherwise coverage is 1700 to 2100. The data range applies to all iPhemeris features.

iPhemeris uses New Style Gregorian Calendar dates starting October 15, 1582 and Julian dates or Old Style prior. However, be aware that various locales adopted the Gregorian calendar at other times; for example, Great Britain didn’t switch until September 1752. Therefore, adjust your dates accordingly.

When using the Extended Ephemeris, enter new style dates after Oct. 15, 1582 and old style dates prior. Currently iPhemeris does not support proleptic Gregorian dates for dates prior to 1582.

We use translation services, but Astrology is a special discipline and many astrological terms have dual meanings. If you notice anything out of context or incorrect in your language please notify support.

iOS Ephemeris Settings

Tropical / Sidereal:

  • Applies to all iPhemeris features (all charts and tables).
  • Selecting Sidereal enables additional Ayanamsa settings to be displayed.

Lunar Nodes: Sets the type of Lunar Node displayed by all iPhemeris features.

Precision: Toggle display of Ephemeris data between DD.MM.SS and DD.MM.

Time Zone:

  • Uses standard Time Zone notation. Locations East of Greenwich are positive (+) and West negative (-).
  • The Ephemeris does not automatically adjust for Summer/Winter time.
  • This Time Zone setting applies only to Ephemeris Displays and Calendars.

Hour: Sets the hour in the Time Zone for Ephemeris and Calendar displays. E.g. if the Ephemeris Time Zone is set for GMT (0) and Hour is set to 12:00, tables display Noon GMT positions.


  • Only appears when the Ephemeris is in Sidereal mode.
  • Tap the Ayanamsa row to choose a pre-defined Ayanamsa and/or use your own value.
  • To set your own value choose Your Ayanamsa at the bottom of the ayanamsa list.
  • The degree offset from Tropical positions for pre-defined Ayanamsa are listed at the end of this documentation. Values shown are for Epoch Jan. 1 2000. iPhemeris adjusts that value to the date of the Chart or Table. It does this using the mean rate of annual precession (0.01396887831940 degrees per year).

Nakshatra Note: This setting is also used by the Nakshatra chart wheel style (see Chart Settings). If you generally display Tropical charts and Ephemeris tables, temporarily enable Sidereal mode, and set the Ayanamsa you want for Nakshatra, then re-enable Tropical mode. Nakshatra will continue to display on the Tropical wheel using the selected Ayanamsa.

Using Your Own Ayanamsa:

  • Tap Ayanamsa row.
  • Scroll to the bottom of the ayanamsa list and select Your Ayanamsa.
  • Tap Settings button to save.
  • Tap the row titled Your Ayanamsa and enter your value for midnight Epoch Jan. 1 2000.
  • To calculate the correct value: ValueNow – ((CurrentYear – 2000) * 0.01396887831940).

When in Sidereal mode, the selected Ayanamsa is used by all features throughout the App.

iOS Chart Defaults

Chart defaults set preferences for how the Chart Wheel looks and also, to pre-populate some fields when creating new Charts.

House System – The default house system used on new charts.

Place – The default location set on new charts.

Use Internet Atlas:

  • ON – iPhemeris presents a Map finding and setting latitude and longitude Requires an internet connection.
  • OFF – wheels are presented that allow manual entry.
  • If you prefer manual entry or an Internet connection is unavailable, turn this OFF.

Show Aspects On Wheel – Toggle ON/OFF display of Aspect Lines in the center of the Chart wheel. This has no effect on reports.

Show House Number – Toggle ON/OFF display of House Numbers on the Chart wheel.

Label House Cusps:

  • OFF – Astrological Signs are displayed in the center of each zodiacal sign and degree marks are shown around the wheel. This gives the wheel a more European style.
  • ON – The point where the house cusp intercepts the sign is labeled in the outer wheel. This can mean that in some cases not every sign is labeled in the outer wheel (but every house cusp is).

Always Show Mc & Asc – Toggle ON/OFF display of Asc, Mc, Ic when those points are the same as one of the house cusps in the House system being used.

Show Minutes on Wheel – Toggle ON/OFF display of minutes on Horoscope wheel. Minutes never display on tri-wheel.

French Wheel Style – When ON this causes the appearance of the horoscope wheel to display in a manner preferred in France. It has the effect of disabling some of the other settings in this section. This wheel style only works for single charts and will revert to other styles and settings for Bi and Tri-wheel.

Dotted Line for Separating Aspects – When ON dotted lines are drawn on the wheel for Separating aspects and solid lines are used for Applying. When OFF, solid lines are used for both Applying and Separating aspects and dotted lines are used for minor aspects.

Degree Marks on Wheel – Toggle ON/OFF the degree marks around outer edge of wheel.

Draw Bold Axis Cusps with Arrows – Draws Bold Arrows on wheel at ASC/DSC and MC/IC cusp.

Show Nakshatra – Toggle ON/OFF display of Vedic Nakshatra divisions (27) with the abbreviation for each. Nakshatra will use whatever Ayanamsa is selected in Ephemeris “Type” settings. If you generally use Tropical charts and Ephemeris tables:

  1. Temporarily enable Sidereal mode.
  2. Select the Ayanamsa you would like Nakshatra to use from the row that appears.
  3. Set the Ephemeris back to Tropical (Nakshatra will continue to use the now hidden Ayanamsa value).

Show Bounds/Terms – Will display the Traditional Astrology “Bounds” or “Terms” around the wheel with either the Egyptian or Ptolemaic rulers.

Decanates – Can be displayed around the edge of the chart wheel in one 4 styles: Off, none at all; Empty thin gray 10 degree segments; Decan containing Modern ruler; Decan containing Traditional Ruler.

Part of Fortune Settings

Choose the algorithm used to calculate Part of Fortune. Most ancient authorities advocated using a different algorithm for day and night births. However, due to a mis-translation of Ptolemy’s writings, a common misconception has crept into modern Astrology causing people to think he advocated using the same formula for both. Recent translations make it clear that he did not. iPhemeris offers both.


Day births occurr when the sun is above the Ascendant/Descendant line, and Night births when it is below.

Different for Day and Night (the default):

  • Day Birth1 = Ascendant + Moon – Sun.
  • Night Birth1 = Ascendant + Sun – Moon.

The Same for Day and Night: 1 = Ascendant + Moon – Sun.

Top ▲

iOS Progression Default Settings

iPhemeris currently provides the two most common Progression styles, more will be added in future.


  • Secondary Progressed – Standard 1 day for 1 year and fraction thereof, since the natal or radix date. All planets are shown in their position on the implied Secondary progressed date and time. You can verify this by looking at the Ephemeris page for the date equal to the number of days after the natal date equal to the number of years since the natal date.
  • Solar Arc in Longitude – All planets are moved the same number of degrees in longitude the Sun moved, using the Secondary Progression technique. Using this style of progression, planets can be in positions they never actually occupied in time and space.


  • Solar Arc in Longitude – The MC is progressed by the Sun’s Solar Arc in Longitude from the natal or radix date to the progressed date. The Ascendant and cusps are calculated from the progressed MC’s implied Right Ascension.
  • Solar Solar Arc Directed – MC, ASC and cusps are moved the same number of degrees in longitude the Sun moved, using the Secondary Progression technique.

iOS Orb Settings

Orbs can be individually set for each of the 4 Features that use them:

  • Charts
  • Sky Now
  • The Aspect Calendar
  • The Transit Calendar

Charts and Sky Now have independent settings for Applying and Separating, calendars use a single orb.

  1. Scroll down to the Orbs section of settings.
  2. Tap the row of the feature you want to set Orbs for.
  3. Charts and Sky Now have independent settings for Applying and Separating, calendars use a single orb.
  4. From the features Orb page tap the Edit button then the row of the aspect you are setting orbs for.
  5. Fractional values of 1/10th of a degree are supported.
  6. To turn an aspect Off, set its orbs to “–” (it is possible to disable either the Applying or Separating side of an aspect setting only that side to “–“).

Top ▲

iOS Sky Now Settings

By default Sky Now and Houses Now use a continuously updating device location. However they can be locked to any specific location you wish, e.g. the New York Stock Exchange.

Place – The location used when Location Services are not available or when the location is locked by turning ON Always Use This Location.

Always Use This Location – locks the location and is used by Sky Now & Houses Now.

iOS Add & Edit Charts

Setting up new charts is fastest if you enter data in the order the fields are presented, top down.

  • When entering the time, enter it exactly as shown on the birth certificate. Do not adjust it for Daylight or Summer time.
  • If you are using the Extended Ephemeris, enter “Old Style” dates prior to Oct. 15, 1582. To switch between BC and AD, simply tap the BC/AD text.
  • Tap Place and you’ll be presented with the Map View to lookup the location.
    • The Map View supports search and scrolling to the location.
    • After you’ve positioned the cross-hairs at the correct location use the Time Zone Lookup button (clock icon) in the upper right corner of the Map View to find the Time Zone.
    • Map and Time Zone lookup require Internet access.
  • Time Zone – This can be set from the Map View or manually from the Time Zone row. Mostly you will use the Find Time Zone button (after date, time and place are set) to get the correct time zone. Only use Local Mean Time for research and old dates.
  • House System – This will be pre-populated with the default house system, but if you wish to change it for this chart you can do that here.
  • Place Name – This is not a place search field, do that from the Map View. It will display the place name if you used place search on the Map View, or you can use it to manually enter or edit a place name.
  • Notes – You can edit and add notes to charts using this. They can also be edited while displaying a chart.

Relocation, Progression & Solar Return

Settings for Relocated, Progressed and Solar Return charts are towards the bottom of the chart data view. Turn the Relocated, Progressed or Solar Return switch ON to draw the associated style of chart. Enter all required information.

When all the required information has been provided, iPhemeris displays the Chart type under in the Chart list, as illustrated below.

iOS Using Map To Find Place

Phemeris uses mobile maps to find Latitude & Longitude for places. It is far more precise than traditional Astrological Atlases and can be positioned to an exact location or address. This is very useful when charts have cuspy issues. Note: Changes in location of only a few miles will noticeably change the Ascendant.

  • Use standard gestures to scroll and zoom to a location.
  • Use the Search Bar to lookup a location.
  • To select a place, position the cross hairs over the desired spot on the map.
  • Use the Time Zone Lookup button (clock, upper right) to get the time zone for the location.
  • Time Zone lookup requires that Chart Date and Time are already set to work correctly.

Note: If you prefer manual entry of Latitude and Longitude, you can turn the Map off in Settings. Set Use Internet Atlas to OFF.

Time Zone Lookup

Time Zone Lookup requires Internet access. iPhemeris uses an international, open source Time Zone database (TZDATA). To get correct values for Astrology charts you must first set the Chart’s Date, Time and Location.

The database is contributed to and corrected by computer scientists all over the world. It was originally created to provide a database that computer clocks could use to know what time zone a specific location used and when (if at all) it switched between regular time and daylight savings time (DST). Due to the various and politically complex dates when places around the world adopted, repealed, then re-adopted Daylight Savings or Summer Time, the database is sometimes off by 1 hour for a specific location. But, because of the continuous revision and improvement (anyone finding an error can report it to TZData committee by providing 3 sources proving the error, e.g. newspaper articles, etc.) it is now probably the most accurate historical record of time zone data and clock changes anywhere in the world for the period 1900 to present.

For US locations, errors sometimes occur (although less and less frequently) for dates prior to 1966 (in 1966 DST was mandated nationwide by law). When errors of this type occur, it is typically that the date for the switch between DT and DST that is incorrect. This will produce an incorrect ascendant caused by Time Zone being off by 1 hour. If you are seeing an unfamiliar ascendant or midheaven value, do a Google search for when Daylight/Summer time was adopted at that place in the specific year of the chart being cast.

It is strongly recommended that you research the date for the DT to DST switch for a US location if you see that iPhemeris is giving an ascendant different from other software. Many programs use an older of source of historical time zone and daylight savings changes (the ACS Atlas). The Atlas part is no longer needed given the availability of highly accurate latitude/longitude location information from Apple and Google Maps API and iPhemeris allows you to find locations using map lookup and which supports most major languages and local place names around the globe.

Unfortunately the Time Zone data in the ACS atlas is known to be extremely error prone, so much so that the developers of the TZ Database (based on the Olson Time Zone database) did an analysis of its accuracy and found it was so error prone they could not use it as a starting source. We have personally documented many errors in that atlas and concluded that the safest approach is to not use it and when a discrepancy arises to do the research. It is simply not wise to rely on, or use ACS, we have found too many errors. Any errors (if and when they occur) will be prior to 1966 in the US and which is becoming less and less important for most people in there day to day research.

You can read more about it on Wikipedia if you wish. It is an important subject for Astrologers to be familiar with.

Usage of iPhemeris Time Zone Lookup:

  • Lookup requires Internet access.
  • Lookup requires that chart: Date, Time and Location have already been set.
  • Find Time Zone – Queries the database for the Time Zone in effect for the data and time at the location.
  • Local Mean Time – Calculates a Time Zone based purely on Longitude. This is only recommended for researchers and very old dates.

iOS Declination & Latitude

The Dec/Lat feature displays standard Ephemeris style, monthly tables of Declination and Latitude for all planets and asteroids included with iPhemeris.

  • The table includes two columns for each body: Declination and Latitude.
  • Displayed values respect the DMS & DM precision Settings.
    • DMS: 25 n 28′ 59″ = 25 degrees North, 28 minutes, 59 seconds.
    • DM: 25 n 29 = 25 degrees North, 29 minutes.
  • Navigation is the same as for the Ephemeris.

Void of Course Moon Tables

Void of Course Moon tables display in the lower left of the Ephemeris and Declination / Latitude displays. The table is included with the Mac Version of iPhemeris, and is available as an In-App Purchase on iOS.

Void of Course Moon
Last Aspect Columns

  • Time Columns – the first 2 or 3 columns show the date and time of the event. There will be 3 columns when GMT, the Ephemeris Time Zone and Local time are not the same, other wise only two.
  • Last Aspect Column – Show the last planet to aspect the moon and the aspect it made.

Lunar Ingress Columns

  • Sign Column – Shows the next sign the moon entered (after the last aspect to its left).
  • Time Columns – 2 or 3 columns listing the time of the ingress event. As above there are 3 columns when GMT, Ephemeris Time Zone and Local time are not the same, other wise two.

The Void of Course period is the time between last aspect and the moon’s entrance into the next sign (Lunar Ingress).

iOS Graphic Ephemeris

iOS Graphic Ephemeris

The Graphic Ephemeris can be added to iPhemeris for iOS with a one-time In-App Purchase. The Graphic Ephemeris adds the following capabilities:

  • A new Graphic Ephemeris tab on the main view that:
    • Display planetary longitude and declination for any date range;
    • Displays harmonic ranges.
  • A new Graphic Ephemeris Report in charts that overlays the currently displayed chart data.

After purchasing you will find the feature activated on the More menu. You can move it wherever you like.


When longitude is selected, standard zodiacal positions for bodies are displayed. Customize what is shown from Settings: Planets & Chart Points.

Data is shown for the selected date range.  Use the toolbar buttons to select a range:

  • The Search button allows selection of any start/end date between 1700 and 2100.
  • The Now button jumps to 6 months either side of now.



Declination can be displayed for the bodies selected in the sidebar by clicking the Declination button in the toolbar. Declination for most bodies is between -30° (south) and 30° (north) degrees of latitude. Use of harmonic ranges does not make sense for declination and therefore the degree range selector is disabled.



If you are not familiar with the display of a graphical ephemeris, it might help to understand for example, that bodies are in Aries when shown on the graph between 0° and 30° and they are in Pisces when between 330° and 360°.

Planets are conjunct where lines cross and they are in aspect to each other when they are separated vertically by the degrees of that particular aspect. For example, if the Sun is on the horizontal line labeled 30° (Aries/Taurus cusp) and Venus is on the horizontal line labeled 90° (Gemini/Cancer cusp) they are separated by 60° and are sextile on that date.

When Moon Phase is selected in the planet selector, New and Full Moon are displayed. New moon is shown where sun and moon lines cross and full moon where they are 180° apart.



The harmonic range selector on the toolbar makes it possible to look for aspects by folding the data over on itself for the selected range. If you are not familiar with how this works, best to leave it set at 360°.

For example, if a range of 90° is set then the vertical scale is restricted to a range of 90° and things at 0°, 90°, 180° and 270° are all displayed at the 0° and appear to be conjunct. This makes it easy to spot aspects for the selected harmonic.

Harmonic ranges can only be used on the longitude display and are disabled when showing declination.

  • Select a date range to display.
  • Display 6 months either side of now.
  • Select a harmonic degree range for Longitude.
  • Declination data cannot be shown with chart data.
  • When a horoscope is selected for display, the positions of the first chart (inner most wheel) are overlaid on the Graphic Ephemeris. These positions are shown as horizontal dashed lines.

Houses Now displays a continuously updating list of House Cusps using the House System and Location specified in Settings. It uses the same settings as Sky Now, set in the Sky Now section of Settings.

  • When Location Services are available it uses current location.
  • When Location Services are not available or it is locked to a fixed location, it uses the Place specified in Settings.
  • iPhemeris is shipped with a default location set to New York City. Change it in Settings.
  • The display updates every 5 seconds.

Note: If location is not updating and you think it should, check that you have allowed iPhemeris to use your location in iPhone Settings.

iOS iCloud Chart Data


iPhemeris can use iCloud to backup and share your astrological chart data between iPhemeris on all your iOS and Mac devices. The first time iPhemeris sees an active iCloud account on a device, it asks if you would like to use iCloud. It only asks once, should you decide to turn it on later, you can do so from iPhemeris Preferences on the Mac or iPhemeris Settings on iOS.

Using iCloud

  • iOS – Requires iPhemeris v9.4 or later.
  • OSX – All versions of iPhemeris on Mac support iCloud.
  1. Enable iPhemeris to use iCloud in iPhemeris Settings (on iOS) and/or iPhemeris Preferences (MacOS).
  2. Allow iPhemeris to use iCloud Drive from iOS System Settings or Mac System Preferences.

iCloud Drive must be turned on and iPhemeris permissioned to use it for you to be able to save and share charts.


iOS – Enable iCloud Drive on iOS

Step 1


Step 2


Step 3


MacOS – Enable iCloud Drive on MacOS

  1. Goto Mac System Preferences.
  2. Select Apple ID in upper right of the preferences dialog.
  3. Select iCloud on left side of Apple ID window. If you do not see it, you may not be using it or signed into and you will have to enable that first.
  4. If you DO see it, select it and then in the window to the right click the Options button next to iCloud Drive.
  5. Find iPhemeris in the list and make sure it is selected as shown in the image below.

Step 3


Handling Duplicate Charts

  1. First, turn iCloud on in iPhemeris on ALL devices you intend to use it with.
  2. Second, allow it to finish syncing all devices. This can take several minutes or hours and it is best to wait until you see all your charts appear on all devices.
  3. Finally, choose one and only one device and delete the duplicates. Deletions will automatically propagate to all your other devices.

Disabling iCloud

This is not recommended. Turning off iCloud means that you will have no backup for your astrology charts and if something happens to your system you will not be able to recover them unless the system is fully backed up some other way.

  • You can disable iCloud in iPhemeris from iPhemeris Settings.
  • Charts will be moved OUT of iCloud and stored on the device locally. Again, we strongly discourage this.

Trouble Shooting Other Issues
We occasionally get blamed for “deleting” your charts. Actually iPhemeris NEVER does that unless you push the delete button on the chart list and delete a specific chart. And if you are using iCloud even deleting the App from one device will not delete your charts.

Some issues we have seen users encounter and which can cause problems syncing with iCloud or even saving charts:

  • Can’t Save Charts
    • Check that you have not reached your iCloud storage quota. If you have, this can cause iPhemeris to silently fail while attempting to save a chart. Often there is an easy solution, simply free up some space by deleting one of the likely thousands of photos you have up there 🙂
    • This can happen if iCloud is ON in iPhemeris Preferences but not enabled to use iCloud Drive. Either turn it on in both places or disable it in both places, as you prefer.
    • Apparently the iCloud sync and storage cache can become corrupt. This can be fixed by simply logging out of iCloud and back in again.
  • Charts Not Syncing – This can occur for a number of reasons including:
    • Not logged into iCloud at all.
    • Not logged into the same iCloud account you saved charts to.
    • You just turned iCloud on and charts have not had time to sync up. After waiting 5 or 10 minutes try a full restart of iPhemeris.
    • On iOS devices check that you have Use Cellular Data turned on. It’s at the bottom of the iCloud Drive screen iPhone Settings > iCloud > iCloud Drive > Scroll to bottom and check “Use Cellular Data”. Be aware this could have an impact on your mobile bill.

Manual Backup & Move


If you use iCloud to store Charts, data is automatically backed up and shared with iPhemeris on other devices. In this case, this topic is not relevant. Note: When using iCloud, iPhemeris can be safely deleted from a device and re-installed without any Chart loss.

Manually Backing Up & Moving Chart Data

Chart data can be manually backed up and also moved between iOS devices. Please be careful when doing this so as to not render the Chart database unusable. This is only possible when iPhemeris is NOT storing Charts in iCloud.

Backup And Move Guidelines

Follow these instructions to prevent damage to the iPhemeris chart database:

  • It is OK to move data between devices running the same version of iPhemeris.
  • It is OK to move data from a device running an older version (lower version number) of iPhemeris to a device running a newer version (higher version number) of iPhemeris. Eg. From 8.6 to 9.0.
  • Never move data from a newer version of iPhemeris to an older version.
  • The safest way to Backup is to use iCloud.
  • When not using iCloud to Backup Charts, save a copy of the files described in the steps below in a safe place.
  • When doing manual Backup, run iPhemeris several times to ensure that it has had an opportunity to update the Chart database. Then make a new backup copy.

Backup And Move Steps

To backup or move data to another device, follow these steps:

  1. Connect the devices you want to move data between, to a Mac running iTunes.
  2. Open iTunes and sync both devices.
  3. Select the device you want to move charts from in iTunes.
  4. On the main panel where Device Summary is showing, select “Apps”.
  5. Scroll down to the “File Sharing” section.
  6. Select iPhemeris in the list and you will see a file called iPhemeris.sqlite on the “iPhemeris Documents” panel.
  7. Copy that file to your desktop using the Save button.
  8. Next select the other device you want to move charts to in the sidebar and navigate to the same panel.
  9. Use the Add button to move the iPhemeris.sqlite file from the desktop to the other device.
  10. Sync the second device again and it will have all the charts you just moved.

WARNING: This completely replaces the Chart data on the second device with charts from the first.
