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.

Seven months ago I was wasting real life minutes (and plenty of willpower) copy-pasting tasks from my Notion database into a separate time-tracking app. Every. Single. Day. One day I spent half of it hunting for a solution, failed, and thought: “Fine—I’ll build it.” Result? - Seamless Notion Database sync - Instantly reflected in Notion Calendar - Built-in Stats dashboard to keep you honest No more app-switching, no more lost minutes—just deep work. Give it a try and tell me what you think!
