—————— Features ——————
Simpluna is an app for recording and predicting your periods.
When you launch the app, a calendar appears so you can check your next predicted period and past periods at a glance. We cut unnecessary features and keep things simple, so the app stays out of your way.
▶ Easy recording
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
Keep notes on how you feel or your physical condition any day.
▶ Notification before the predicted date
Get notified as your next predicted period approaches. Choose how many days in advance and at what time.
▶ Register up to 1 year of past data
If you have past period records, you can register them going back up to 1 year from when you started using the app. (Simpluna Plus extends this to 10 years.)
▶ Forecast calendar up to 1 year ahead
Look up to 1 year into the future. You can also save future plans as notes and view them alongside predictions.
▶ List of past periods
Review your past periods as a list.
▶ Data backup
Sign in to back up your data. Useful when switching devices or if you accidentally delete the app.
▶ App lock
Lock the app with a 4-digit passcode if you do not want others to see it. Face ID is also supported.
▶ Dark mode support
The UI colors switch to match light or dark mode.
▶ Works offline
The app works even when offline or with a poor signal.

—————— About pricing ——————
Simpluna is intended as a tool for everyday use. With that in mind, we chose a one-time purchase rather than a subscription for the paid features.
Some of you may wish to use more features (such as ovulation tracking or color themes) for free. The free set is kept minimal because we do not display any ads, in order to keep the user experience good. An ad-free experience matters more than having more free features alongside constant ads.
We have set the price to be as affordable as possible. If you have any feedback or requests, please feel free to contact us.

After being recommended several different period tracking apps, this one is far superior for my needs. It is exactly what was looking for; simple and easy to use. I am past the point in my life that I need to track ovulation, and wanted something that would remind me my period is coming, have a calendar to show, and calculate when based on my average challenge is. As a woman that is in the beginning stages of perimenopause, my period is no longer as predictable as it once was. The three day until period starts is a such a wonderful feature with them beginning to become a little closer together. I highly recommend if you are in the same point in your life as I am, and want something straightforward to use.
I’ve been looking for this!

I installed six other apps before I found this one. This app is finally the one I was looking for! It’s simple, and has notifications that work effectively. It doesn’t have a lot of distracting information on it, so I can clearly see what I need when I open the app. Thank you! The one time purchase of Simpluna plus was also a huge win for this app. So many apps for period tracking had unnecessary features that came at a monthly cost. And this app is not only simple and clear, but its design is also calming and sophisticated!
Perfect!

This app is perfect, I have no qualms whatsoever. It figured out my cycle faster than I’d expected and now is perfectly lined up every time. It doesn’t ask me all those questions about like blood flow and other symptoms that I overthink which is great, but still has a space for notes which I love to use to write symptoms and sometimes around when it started. It’s great and exactly what I want in a period app! It also lets you set a lot of notifications to remind you when it’s coming up. So so happy I got it, no more soiling my clothes for me!
GREAT for just a simple period tracker

I was looking for just a period tracker, none of the “most fertile now” kinda stuff and i would say this is a great app for that! It’s completely free, no adds and I love how easy it is to mark when your period started and when it ended and you can take little notes on how it was. It really helps to get an idea of what is normal when you’re on your period! I would say that it is great for teens who are just starting their cycle or it could be good for adults who have had their cycle for a while.
