About
iPhemeris Astrology Software
iPhemeris is professional Astrology software for iPhone, iPad (iOS) and Mac (MacOS). It includes full astrological charting, chart reports, iPhemeris AI Advisor, AstroCartography, a traditional book-style tabular Ephemeris, Lunar tables, Astrological Calendars, Sky Now real-time charting, Graphic Ephemeris, and complete Tropical or Sidereal calculation modes.
iPhemeris uses the Swiss Ephemeris, based on JPL DE430/431 ephemerides, and includes traditional tabular Ephemerides with tables of Longitude, Declination & Latitude, Moon Phases, Eclipses & Void of Course Moon data. It can be set to display positions for any time and time zone you choose. Need a 9:30am ET Ephemeris for the New York stock market open? No problem.
Vedic Astrologers love iPhemeris because everything can display Tropical or Sidereal positions for any of 17 pre-defined Ayanamsa, or set your own.
iPhemeris was the first Astrology App for iPhone and has been continuously updated and improved since its introduction in 2008. If you’re serious about Astrology and need detailed, professional-level tools for calculation, research, chart work, interpretation, timing, and location analysis, iPhemeris is what you’ve been looking for.
Features
The Mac, iPhone, & iPad Versions Have the Same Capabilities
iPhemeris now includes a powerful new capability: iPhemeris AI Advisor.
For the first time, iPhemeris goes beyond charts and calculations to provide complete professional-level interpretations directly inside the application. AI Advisor analyzes the charts stored in your iPhemeris database and delivers detailed astrological insight instantly.
AI Advisor evaluates the full structure of a chart, including:
- Planetary placements
- House cusps
- Aspects and aspect patterns
The result is a comprehensive interpretation of the chart’s dynamics, written in clear professional language suitable for both serious students and practicing astrologers.
Unlike static interpretations, AI Advisor is fully interactive. After generating a report, you can continue the discussion with the AI—ask follow-up questions, request deeper analysis, or explore specific themes in the chart. The AI may also request additional context to refine its interpretation.
This interactive approach allows you to investigate any dimension of a chart, including:
- Relationships and compatibility (synastry)
- Life timing and transits
- Personal development
- Health and medical astrology
- Psychological and spiritual themes
- Practical life questions and decision timing
Because AI Advisor works directly with the charts already stored in your iPhemeris database, it becomes a research and interpretation partner, helping you explore charts more deeply and efficiently than ever before.
With iPhemeris AI Advisor, your chart database becomes not just a collection of charts—but a living resource for continuous astrological exploration.

The Graphic Ephemeris is one of the major research tools in iPhemeris. It lets astrologers visualize planetary movement over time instead of reading positions only from tables. This is especially useful for studying long-range patterns, repeated contacts, retrograde cycles, declination movement, and the timing of important transits.
Use the Graphic Ephemeris to see how planetary motion unfolds across days, months, years, or longer periods, and to compare those movements with stored charts from your iPhemeris database.
- Display Longitude or Declination for any date range.
- Display any harmonic degree range between 30° and 360°.
- Overlay astrological charts on the graph.
- Study transits, retrograde loops, repeated contacts, and longer planetary cycles visually.
- Use Graphic Ephemeris together with chart reports, transit calendars, tabular ephemeris data, and AI Advisor analysis.
- Helpful for professional timing work, forecasting, research, and identifying patterns that are harder to see in tables alone.
iPhemeris includes AstroCartography for exploring how natal, relocation, and planetary angularity themes shift across the world. AstroCartography maps help astrologers evaluate locations by showing where planets become angular on the Ascendant, Descendant, Midheaven, and IC.
Use AstroCartography to investigate relocation questions, travel, professional visibility, relationship environments, life transitions, and geographic themes in a chart. For professional astrologers, it adds a visual layer to the same chart database already used for wheels, reports, transits, progressions, returns, and AI Advisor analysis.
