Plum: Period & Cycle Tracker

Your cycle stays on your phone, not in the cloud. Track periods, moods, and symptoms in a calm space with no account and no sign-up

A calm, private period tracker that keeps your cycle on your iPhone. No account, no sign-up. Just your periods, moods, and patterns in one quiet place.

WHAT PLUM DOES Plum predicts your next period, fertile window, and ovulation, and the estimates get sharper with every cycle you log. Log flow, symptoms, mood, and notes in seconds. Your whole month shows up on a color-coded calendar, so you can see bleeding days, predicted periods, and what's coming next at a glance.

The mood wall lets you check in on how you feel, and fill in the days you missed. Connect Apple Health and Plum shows your cycle phases next to wrist temperature, HRV, sleep, and resting heart rate.

PRIVATE BY DESIGN Your cycle data stays on your device, not in our cloud. There's no account to make and no email to give us. You decide what to log and what to skip, and you can change any of it later.

Some cycle apps got caught handing period data to advertisers. Plum is built so there's nothing to hand over.

CALM, NOT CLINICAL Soft colors, gentle words, and only the things you asked for. No fertility funnels, no pressure, no judgment about what your body is doing.

GENTLE INSIGHTS Plum reads your logs and signals to offer estimates, never diagnoses. The more you track, the better it learns your rhythm instead of fitting you to a textbook.
