Petal: Period Tracker

A calm, private period tracker that works entirely on your phone.

No account. No sign-up. Nothing is uploaded. Your cycle data stays on your device — that is not a setting you have to find, it is how the app is built.

TRACK
• Period days and flow intensity
• Symptoms, mood, energy and sleep
• Intimacy and test results
• A private note for any day

UNDERSTAND
• Cycle day and current phase at a glance
• Next period estimate with a confidence indicator that reflects how regular your cycles are
• Fertile window and estimated ovulation day
• A hormone reference chart for the phase you are in — an illustration of typical patterns, not a measurement of your body
• Averages and trends across your logged cycles

PREGNANCY MODE
Switch it on and the app follows the pregnancy week instead of the cycle, with an estimated due date. You can enter how many weeks along you already are, so it works even if you start late.

REMINDERS
Optional reminders before your period is expected, a check-in when it should have ended, and a daily logging nudge. Discreet mode keeps every notification vague, so a glance at your lock screen gives nothing away.

APP LOCK
Lock the app behind your fingerprint, face or device PIN. It re-locks whenever you leave.

COMING FROM ANOTHER APP?
Import your history from an Apple Health export, or from a JSON or CSV export from other period apps. Everything is read on your device, and your existing entries are merged, not replaced.

11 LANGUAGES
English, Turkish, German, French, Spanish, Italian, Portuguese, Russian, Polish, Ukrainian and Dutch.

FREE
No ads. No subscription. No in-app purchases. Every theme is included.

All predictions are estimates based on the days you log. This app is not a medical device and not a method of contraception. It does not diagnose or treat anything — talk to a clinician about medical questions.
