Simpluna is a simple period tracker app. Use it as a menstrual cycle tracker to record period dates and check predictions at a glance. When you launch the app, a calendar appears so you can check your next predicted period and past periods. 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. Biometric authentication is also supported.
