My Period AI: Cycle Tracker

My Period AI is an AI period and cycle tracker for iOS that learns an individual's real cycle patterns instead of assuming a standard 28-day cycle. It improves its predictions over time from a user's own logging, making it aimed at people with irregular cycles or PCOS who find template-based trackers inaccurate. Core features include daily logging, a visual insights dashboard, relaxation games, and an AI wellness coach that personalizes its responses to the user's data. Privacy is a stated focus: the app uses end-to-end encryption, is GDPR compliant, carries no advertising, and says user data is never sold — "private by design." It is free on iOS. Because the app's marketing detail comes largely from its Product Hunt listing rather than a full homepage, feature specifics beyond the above should be confirmed in-app.
