Period Tracker is a calm, privacy-first way to track your menstrual cycle. Everything stays on your device — no account, no cloud, no sharing, ever. PRIVATE BY DESIGN Your data never leaves your phone. There's no sign-up, no server, and no tracking. Everything you log is stored locally, and deleting the app deletes all of it. Period Tracker contains no analytics, no ads, and no third-party trackers. ONE TAP A DAY Log your flow, mood, and symptoms in seconds. Periods are figured out for you from the days you log — no need to mark start and end dates manually. The app learns your pattern over time. SMART, GENTLE PREDICTIONS See your predicted next period, fertile window, and ovulation day, plus a confidence range that adjusts as you log more. A cycle ring on the Today screen shows where you are in your cycle at a glance. These are educational estimates, not medical advice. STAY IN THE LOOP Optional local reminders — scheduled entirely on your device — can alert you before your period, on period day, at the start of your fertile window, and on ovulation day. You choose the time and how many days ahead. EVERYTHING IN ONE PLACE • Today — your cycle ring and a timeline of what's coming up • Calendar — a clean month view with your logged days and predictions • History — a reverse-chronological journal of your days, filterable by flow, mood, and symptoms • Insights — averages, trends, and a "count as period" toggle to fine-tune predictions NO ACCOUNTS, NO CLOUD, NO WORRY Period Tracker works completely offline. There is nothing to sign up for and nothing that can be leaked or sold, because nothing ever leaves your device. Note: Period Tracker provides educational estimates only and is not a medical device or a substitute for professional medical advice. Always consult a healthcare professional for health decisions. Requires iOS 17 or later. Works on iPhone and iPad.
