Safe Days: Cycle & Fertility

Safe Days shows the days of your cycle when you are most and least likely to get pregnant, using the calendar method. It learns from the periods and body signs you log, warns you when something needs care, and keeps everything on your phone. YOUR CYCLE AT A GLANCE • A ring of your cycle shows today: period, fertile or safe • A colour calendar marks period, fertile, safe and expected days • See when your next period and next fertile window are due TRACKS AND LEARNS • Log your period, flow, sex, symptoms, mood, waking temperature, weight and notes • After 3 cycles, Safe Days works out your fertile window from your own history • Prefer not to track? The quick calculator works from your last period and cycle lengths alone WATCHES FOR BODY SIGNS • Log cervical mucus and ovulation tests • A fertile sign marks the next days "take care", even when the calendar says safe • Your temperature chart shows the rise that follows ovulation • Cycles outside 26 to 32 days are flagged, because the method is less reliable then REMINDERS • Before your period, before your fertile window, and when safe days begin • An evening reminder to log your day • Discreet mode keeps words like "period" and "fertile" off your lock screen PRIVATE BY DESIGN • Your cycle data stays on your phone: no account, no server • Lock the app with your fingerprint, face or PIN • Swap the icon for a plain calendar • Back up to Google Drive or anywhere you choose INSIGHTS AND A DOCTOR REPORT • See your cycle lengths and temperatures over time • Make a PDF summary or a spreadsheet to share with a doctor or health worker FREE, WITH AN OPTIONAL PRO The calendar, logging, warnings, insights and reminders are free.
