About this app

The feature is simple. When you enter your period date, the next period date is predicted and displayed on the calendar. It doesn't show Ads, columns, and the best time to lose weight. It simply tells you when your period is due.

Simpluna is an app for recording and predicting menstrual days. Launch the app to display a calendar where you can check your next predicted menstrual period and past menstrual days at a glance. Simpluna has an extremely simplified design, eliminating all unnecessary features to ensure it does not interfere with your daily life.

Simple and easy to use. To input your period days, just tap a date on the calendar and select the start or end button. No need to learn the app. You'll know how to use it instinctively.
Leave notes on the calendar's dates. You can keep track of your physical condition or state using the memo feature.
Get notifications when your next predicted period is approaching. You can also specify when or how many days in advance you'll be notified.
Record your past periods. You can record menstrual periods up to one year before starting the app. If you purchase Simpluna Plus, you can register up to the last 5 years.
Predict your periods up to one year ahead. You can take note of your future periods and check them with the forecast calendar feature.
・Also functions offline or under poor internet conditions.
No ads nor promotional material.

The below features require a fee. You will need to purchase Simpluna Plus (once only):
Color Themes🎨
Ovulation Day Prediction🥚
PMS Period Display😑
Prediction Summary Display📝
Customizing Input Fields (for example, 'Symptoms', 'Body Temperature', 'Pill Taking', etc.)📝
Customizing Notification🔔
Pill Reminders💊
Widget (Small and Medium size)📱
Historical Data Registration (last 5 years)📊

We provide Simpluna to be a tool that users can easily use daily. Therefore, we have determined that subscriptions for paid features would not be desirable and only charge customers once.

You might want to use some more features for free, such as ovulation day management, color themes, etc. The minimal number of free features is because we do not display any ads to improve the user experience. We believe that it is more important to be able to use an app without ads and stress than to have ads constantly displayed and many functions for free.\n\nWe have kept the cost of the app to the bare minimum; however, don't hesitate to reach out should you have any concerns. We would love to hear your opinion.

I think that vertical scrolling of the calendar would be better than horizontal. Flo (app I am switching away from) uses vertical scrolling which I appreciate, as it is much easier to maneuver longer time periods via continuous vertical scrolling. I like how simple the app is, yet still configurable - Flo is excessive for me, but Simpluna lets me only show what I want so it isnt cluttered, and it isn't ugly! Ability to export data in a format helpful to medical professionals would be nice.

I tried this app after Clue failed me. Love the clean interface and minimalist design. However the app is sort of laggy. There is always a delay after every click. Fix that and I will give it 5 stars. Edit: while the app offers much more tracking customization than other apps, it doesn't provide as much insights, even with the Plus version. I'd like to know if my menstrual health is normal or not, at least. The app does nothing more than tracking, which is a bit underwhelming.
