TeenCycle
Private, offline period tracker. Pay once, no account.
TeenCycle is a period tracker that runs entirely on your phone. No account, no cloud, no analytics, no ads — nothing ever leaves the device, so there is nothing for anyone to sell, leak, or hand over. Three screens, one tap to log, and a calendar that estimates when your next period is likely. A mom and her teenage daughter built it for teens, but it works for anyone who would rather not be tracked. Free for 7 days, then $9.99 once. Never a subscription. On iOS and Android.
Hi Product Hunt. I'm Laura — one half of the family that made TeenCycle. The other half is my teenage daughter, Mia.
It started at our kitchen table. Mia was about to start tracking her period, and we went looking for an app we could both trust. What we found wanted her email and a login before she'd logged a single day. Some asked a young teen about her sex life. Most had feeds to scroll and streaks to keep, quietly sending her most personal information to a server somewhere. For a period tracker.
So we stopped looking and built the one we wanted:
— 100% offline. Everything stays on the phone. No account, no cloud, no analytics, no trackers. There's nothing on our end to sell, leak, or hand over, because we never have it.
— Three screens, one tap to log. No feed, no notifications, no streaks. Open it when you need it, close it when you don't.
— One honest price. Free for 7 days, then $9.99 once. Never a subscription.
My husband built exactly what we asked for, and nothing we didn't. We're not a startup with investors or data to sell — just a family that built the tracker we couldn't find for our own daughter.
It's made for teens, but it works just as well for anyone who'd rather not be tracked. The predictions are estimates that get better the more you log; it isn't a medical tool, so please talk to a doctor if something feels off.
We'd love your honest feedback — on the design, the privacy model, and what you'd want from a tracker that holds nothing. I'll be here all day to answer.

The origin story is genuinely touching - building this for your own daughter is the best possible reason to start. But one real concern: purely offline with no export means a lost or broken phone wipes months of cycle history. For teens especially, continuity matters.
Is there any local encrypted backup on the roadmap - export to Files app, AirDrop, etc.? That one feature would significantly lower the stakes of going fully phone-only.
We're #17 wow. Thanks for the support!
Thanks for the votes! From #94 to #27. Thank you!
