PeriodPal is the period tracker built for two. You log your cycle once. The people you invite see it on their own phones the moment you save it, read only.

Shared the instant you log it

Mark a period day with its flow, add symptoms, mood, sexual activity, or a note. Whoever you have invited sees the update immediately. No screenshots, no recap texts. You log it once and the person supporting you already knows.

You decide who sees it

Sharing starts with an invite link that works exactly once, for the person you sent it to. Viewers get read only access: they can see, never edit. Share with a partner, a parent, anyone you trust, and each one separately.

Revoking is instant and total

Remove a viewer in one tap and they lose everything that same moment: your history as well as anything new. No grace period, no leftover copies in their app.

Quiet on their lock screen

When you log, your viewers get a notification that just says “New update”. No cycle details on anyone's lock screen unless that viewer opts into more on their own device. Your notes are never included either way.

Honest estimates, not prophecy

PeriodPal projects your next periods from your own cycle lengths, and marks an estimated fertile window and ovulation day for each one. Estimates from your dates and nothing else: no conception coaching, no pregnancy scoring, never a contraceptive method, and no pretending to know more than the data does.

Private on purpose

No ads, no data brokers, ever. Nothing you log is sold or rented. Your data is encrypted in transit and at rest, and your cycle is shown only to you and the viewers you chose. Deleting your account is a real delete: every log, every share, every invite, gone. We do collect usage analytics to understand how the app is used — the privacy policy sets out exactly what that includes.

Track free, share with Plus

Everything you do on your own — logging, the calendar, predictions, your whole history — is free and always will be. PeriodPal Plus turns on the sharing: monthly or yearly with a one-week free trial, or a one-time lifetime purchase. Only one of you needs it, and it doesn't matter which: whoever subscribes, both of you see the cycle.

  • The home screen in the dark theme: a ring of overlapping petals around a large 8, reading days until next period on Tuesday August 11, above an August 2026 calendar with the predicted period drawn as a band across the 11th to the 16th.
  • The day sheet for Saturday July 18, listing sixth day of period, five days until the fertile window and ten until ovulation, with period flow set to medium and the symptoms cramps and nausea ticked.
  • The per-viewer sharing controls, headed four things hidden: switches for symptoms, mood, notes, energy, lifestyle and discharge turned on, and sexual activity, skin and hair, contraception and pregnancy test turned off.
  • The stats screen on its timeline tab, July 2026, with a card per logged day — Saturday the 18th reading medium flow, cramps, nausea, tender breasts, anxious, irritable and medium energy.
  • The same home screen in the light theme, cream rather than near-black, the petal ring reading eight days until the next period above a July 2026 calendar with the period drawn from the 13th to the 18th.
