Period Tracker - Free period tracker with an AI that knows your cycle

by•3h ago

Period Tracker is a free web app for logging your period, symptoms and moods. Its AI chat, called Ask, reads your own cycle history and answers questions in plain words, from first period basics to what your logs show. Each month you get a report with tips based on your records. You also get email reminders before your next period, alerts when cycles turn irregular, partner sharing and 21 calculators that work without an account. It runs in any browser with nothing to install.

Hi Product Hunt,

Period Tracker started as a few simple calculators that work in the browser with no sign-up. Over time people who used it every month began writing in with requests, and most of what you see today came from those emails.

The newest feature is Ask. A reader wrote to us asking for an AI chat inside the tracker, so we built one. Ask reads a summary of your own logs, so you can ask things like "Is a 38 day cycle normal for me?" or "Why did my period come early this month?" and get an answer about your cycle instead of a generic one.

Some of our users are teens who just had their first period and have no one to ask. So Ask sticks to period and cycle topics, leaves fertility details out for anyone under 18 and tells you to see a doctor when something sounds serious.

With a free account you can also:
- Log your period, symptoms, moods and notes
- Get a monthly report with tips based on your own records
- Get email reminders before your next period
- Get an alert when your cycles look less regular than usual
- Share your cycle with a partner and choose what they see

All 21 calculators still work without an account.

I'd love to hear what you think, especially if you try Ask. What would you ask it first?
