Track your cycle with complete privacy. Your data stays on your device — no accounts, no servers, no surprises.
Your data, your rules
Iris stores everything on your device using iOS's secure local storage. Period dates, symptoms, mood, and notes never leave your phone unless you choose to sync via your own iCloud account.
No tracking, no ads (paid)
The free version shows non-targeted ads via Google AdMob. Upgrade once to remove all ads permanently — no subscription, no ongoing charges.
Sign in with Apple
Optionally use Sign in with Apple to link your data to iCloud for multi-device sync. Iris only stores an anonymous identifier — we never receive your email or personal information.
