—————— Features ——————
Simpluna is an app for recording and predicting your period days.
When you launch the app, a calendar appears so you can check your next predicted period and past periods at a glance. By cutting unnecessary features and keeping things as simple as possible, we make sure the app does not get in the way of your daily life.
▶ Easy recording
To record your period, just tap a date on the calendar and press the start or end button. It is intuitive, so there is nothing new to learn.
▶ Notes on each day
If there is anything you want to keep track of, such as how you feel or your physical condition, you can leave it as a note.
▶ Notification before the predicted date
You can receive a notification as your next predicted period approaches. You can specify how many days in advance and at what time you want to be notified.
▶ Register up to 1 year of past data
If you have past period records, you can register them. The available range goes back up to 1 year from when you started using the app. (With Simpluna Plus, you can register up to 10 years.)
▶ Forecast calendar up to 1 year ahead
The forecast calendar lets you look up to 1 year into the future. You can also save future plans as notes and view them together with the predictions.
▶ List of past periods
You can review your past periods as a list.
▶ App lock
You can lock the app with a 4-digit passcode if you do not want others to see it. Face ID is also supported.
