Stardust App

You log your cycle in Stardust App and get back predictions, hormone explanations and personalized insights about your mind, body and spirit.

Stardust App is a free period, ovulation and pregnancy tracker that blends science with astronomy, and it was built by women.

Your data is encrypted, which matters for an app that holds this kind of health information.

The astronomy angle is the main thing that sets Stardust apart from plainer cycle trackers.

It draws on ancient wisdom and folklore to explore what it calls menstrual-lunar synchronicity, so expect a more spiritual tone than a clinical one.

You can also sync cycles with friends.

There is a separate Stardust App Shop that sells merchandise related to the app.

The app itself costs nothing to use.
