Real compatibility, not just sun signs
Iris reads the full picture — synastry (chart-to-chart) and composite (your shared chart) — and scores it across five dimensions: Harmony, Passion, Connection, Stability, and Growth.

Questions
The short version. For more, see Support.
What is Iris?
An astrology app for understanding romantic compatibility. You build your own profile from your birth chart, add the people in your life, and see how you connect — using synastry (chart-to-chart) and composite (shared-chart) astrology.
How is compatibility scored?
Across five dimensions — Harmony, Passion, Connection, Stability, and Growth — read from the way two charts actually relate, not just sun signs.
Do I need an exact birth time?
No. You can mark a birth time as unknown and Iris still calculates a chart and compatibility — some house-based details are simply less precise without it.
Is my data private?
Yes. Your birth and relationship details are used only to generate your readings. We don't sell your personal information or use it for third-party ads. See the Privacy Policy for details.
What does it cost?
New members start with free credits. You can top up with credit packs or subscribe for unlimited everyday use — $14.99/month or $99.99/year. Purchases are handled securely through your Apple ID.
