Why people choose Simpluna
Want to leave subscriptions behind
The app is free to use, and Plus is a one-time purchase.
I’m also happy that the paid version is a one-time purchase rather than a subscription, which makes it easy to buy.
Want to keep it simple
Just logging and predictions. No diagnoses or articles.
Simple. The free version is a calendar that just shows when your period will be or has been, and notifies you a few days before. Exactly what I wanted. Other apps have too many features for my taste.
