Planned Parenthood’s #1 Period Tracker

The #1 period tracker for all you love and care about.

A comprehensive menstrual tracker powered by the experts at Planned Parenthood.

You don’t have to rely on your phone’s “period tracker” or “period tracker app” — you can now have your periods tracked by our experts, right from the app.

From scheduling birth control, to getting tips to get you through a challenging time, to finding birth control and getting your questions answered, our team of sex educators has you covered.

Whether you’re on your pill, patch, IUD, vaginal ring, or you’re not on birth control, Spot On can accurately predict your period and give you a heads up on when you’re likely to be fertile.
