  I made a privacy friendly and simple app to track my menstruation2024 · play.google.com · ▲732

  Hey HN, after the app I actually used to track my period wanted me to log in and save my data in the cloud, I decided to write my own. Most apps in this area are based on a subscription model and display far too much information anyway. For me, a simple calendar is enough where I can add a few notes if necessary. So that is the result of my work - a simple design and the data is only saved on the smartphone.
