This app has been very helpful! It has many many many options, has no adds, and has plenty of privacy. It is free and is the best period calendar I have ever gotten. You can always delete data, which I find very helpful. It also helps tell you how you can get rid of cramp pain and helps you with mood swings, really any pain, emotions, support, ect. I deeply think that you should get this app, it is very helpful. And if you don't like something on it you can always change it or contact them.

its been very helpful to have all this info at my fingertips. I did something wrong when I was trying to change my profile to my name and now my profile is gone and I'm not sure how to restore the back up. I've soent ten minutes looking for some way to restore my backup and NADA. Is a "restore data" not possible? All this to say, it's not intuitive outside the calendar part. I also paid $2.99 to remove ads but still have them. The app is OK, but when I run across a better app, I'll switch.

I have been tracking my period in this app for over 12 years (147 cycles). I'm very pleased with the interface, the customizable themes are very cute. I like being able to track other things like how I'm feeling, migraines etc. so you can recognize trends over your cycle. I think the smartest feature is that if you forget to track a period, the app still assumes that it occurred and predicts the next one like normal. Overall I'm very happy and I highly recommend this!
