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.

This app if user friendly, and very accurate. it almost always predicts the start of my cycle and if it is off, it's usually by a day or so. I like that I can log symptoms, mood and water reminders. It would be perfect if there was a partner feature so that the cycle could be tracked by a spouse and if the app would track the phase of the cycle you're currently in.

it's a good period tracker, mostly accurate in my opinion, it's a good one, and of course I don't always expect it to be accurate, things change and people's bodies change but I like it cause your partner can see it too, you can put your mood on there, so your partner can know if you dont want to talk about it, this is just a good app, and great for teenagers especially the other ones I tried you either had to be pregnant or in menopause as an adult, but it's mostly accurate.
