What is drip?

drip is an open-source period and fertility tracker that keeps your entries on your phone, not in the cloud 🌱🩸 Log bleeding, temperature, cervical mucus and cervix, sex, desire, pain, mood and notes, and switch off any category you don't need. After three full cycles it predicts your next three periods, and for fertility awareness it uses the symptothermal method, with calculations you can read in its published source code. It's a non-commercial volunteer project of Heart of Code e.V. in Berlin, with no ads, built with gender inclusivity in mind.
