Hello Cycle vs Cycle & Period Tracker

Understand your cycle with iPhone and Apple Watch. Hello Cycle helps you record periods and daily symptoms, follow your own patterns and prepare for your next period. • Estimates informed by your body: optionally connect Apple Health to use sleeping wrist temperature, resting heart rate, HRV and sleep summaries alongside cycle history. Calculations run on your iPhone. A compatible device, health permissions and enough data are required; timing and accuracy vary. • Simple records: start or end a period, correct past dates, and log flow, pain, mood, custom states and notes. See recorded periods, predicted periods and estimated ovulation in the calendar, and explore trends in Insights. • Apple Watch companion: record quickly, view cycle information in watch-face complications, and sync with your iPhone when the devices reconnect. • Privacy and control: Sign in with Apple before getting started. Privacy-filtered records sync automatically to your account; raw and daily health measurements are not uploaded. Export a PDF, set reminders, or delete your account in the app. Start with a free trial confirmed through Apple's purchase screen. After the trial, continued recording, predictions and insights require a one-time Lifetime VIP purchase. Existing records remain available to view, export and delete. Additional illustration series require Lifetime VIP. No subscription or automatic renewal. See the in-app Apple purchase screen for trial terms and local prices. For personal records and wellness reference only. Predictions are estimates, not guarantees. The app does not provide medical diagnoses, confirm ovulation, or support contraception or fertility decisions. Consult a qualified healthcare professional with health concerns.
