About
Petal is a period tracker that never asks who you are.
No account. No cloud. No sign-up screen. Your cycle, your symptoms, your moods — all of it stays on your phone, your cycle history is encrypted, and Petal never sends any of it to a server. That is not a setting you have to find. It is how the app is built.
WHAT IT FEELS LIKE TO USE
Open Petal and you see one thing: a soft circular ring showing exactly where you are in your cycle, and how many days until your next period. Tap a flow, a symptom or a mood to log today. That is the whole daily interaction — about five seconds, and it is the only screen you need most mornings.
PREDICTIONS THAT ARE HONEST WITH YOU
Petal tells you when your next period is likely, when your fertile window opens, and when to expect ovulation and PMS. For your next period it also tells you how confident it is, and shows a range rather than a single reassuring number. If your cycles are irregular, it says so instead of inventing certainty. Everything sharpens as you log more.
WHAT YOU GET BACK
Over a few cycles Petal builds a picture: your average cycle and period length, how much they vary, and which symptoms and moods cluster in which phase. When you need it, one tap produces a clean PDF health report to take to an appointment. Tap a finished cycle for its recap: how long it ran against your usual, its heaviest day, and the symptoms and moods you logged most. And you can search every note, symptom and mood you have logged, right on your phone.
There is a trying-to-conceive mode with a fertile-window focus, a basal temperature chart and ovulation-test logging, and a simple pregnancy mode for when the time comes.
PRIVACY YOU CAN ACTUALLY CHECK
Lock the app behind a PIN or Face ID. Turn on discreet mode so nothing shows in the app switcher. Take an encrypted backup you hold yourself. Delete everything from Settings, with nothing left behind on a server, because there was never a server.
Reminders are opt-in and individual: period soon, period late, pill, a nudge to log, and fertile-window and ovulation reminders in trying-to-conceive mode. Choose only the ones you want.
WHAT IT COSTS
Nothing to use. Tracking, predictions, insights, PDF export, app lock and backup are all included, with no subscription, and no feature is ever locked behind a payment. Ads support the app: banners on Calendar, Insights and Me, a card in Learn, and now and then a full-screen ad when you come back to the app, never while you log a day. If you want a quiet stretch, one short ad turns them off for a day. Choose from six app themes in light and dark: Petal is yours from the start, and Lavender, Peach, Ocean, Sage and Sand are each yours for good after one short optional video. Optional Petal Pro is a one-time purchase that removes the ads for good and includes every theme; every tracking feature stays free either way.
Petal is a small, careful app for something that matters. We hope it feels that way.
Note: Petal is a self-tracking and educational tool. Predictions and fertile-window estimates are not a reliable form of contraception and are not medical advice. Please talk to a clinician about any health concerns.
