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.

Simpluna▲68I've been running Simpluna, a period-tracking app, for six years. It's a company based in Tokyo, Japan, but development and operations are basically a one-person effort. The app is built with React Native (Expo). The defining trait of the app is that it's simple, with no unnecessary features. 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).

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. Not long after, she started getting eerily specific suggestions on other platforms. Things she hadn’t searched for. Things that felt too close. Somewhere, her cycle had been turned into a data point. That bothered me more than I can explain. These apps promise helpful insights. But in return, they take so much.…
