What it does

Simpluna is a simple period tracker with no ads and no account. Enter your period dates and the next period is predicted on a clean calendar. Private by design: your period data is stored only on your device, and nothing is required to start — no sign-up, no email, no personal profile. Cloud backup is optional and stays under your control. You can also lock the app with a passcode or Face ID. The paid Plus version is a one-time purchase, not a subscription. Over 600,000 downloads.

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). Building something similar would have been hopeless, so I made the things those apps don't have my selling point. Optional features…
