Everything, gently

Understand your body,
one calm tap at a time

Made for first periods

A calm, judgement-free guide to a first period: what’s normal and how to use pads, tampons and cups. Always free.

Track in seconds

Start and stop your period with one tap, on iPhone or Apple Watch. Log flow, mood, symptoms and notes in moments.

Smart predictions

Period and ovulation forecasts that learn your rhythm and are tuned to your age, with a cycle-phase view of right now. Predictions are estimates, and never a form of contraception.

Insights that add up

See your cycle length, regularity, top symptoms and mood patterns, and track sleep alongside your cycle.

Share with your doctor

Export a clean PDF report of your cycle, generated privately on your device and anonymous by default.

Private by design

Questions

Good to know

Is it really free?

Yes. Period tracking, the calendar and every first-period guide are free, always. An optional Premium unlocks the daily Log and Insights tabs and the doctor report. No ads either way.

Do I need an account?

No. Simply Track works entirely on your device, with nothing to sign up for and nothing stored in the cloud by default.

Is it good for a first period?

That is exactly who it is built for: gentle guidance, plain answers, and predictions that adapt to a still-settling cycle.
