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.

Recording periods, calculating predictions, and sending notifications — that's the core of it. This space is dominated by big players (Flo, Clue, and in Japan, Luna Luna). Building something similar would have been hopeless, so I made the things those apps don't have my selling point. Optional features…

There’s something quietly unsettling about how normal it's become to hand over our most personal data to apps that barely deserve our trust. My wife once showed me a notification she got from her period tracking app. At first, it seemed like a simple reminder. But then came the ads.
