Great and useful app

It does exactly what it’s meant to do - keeps track of your period and I love the fact you can keep track of your moods too! It’s like giving yourself a bit of therapy by picking the ones that describe how you feel and when you look back you can see that actually that’s when your ovulating and the same happened the month before and it all makes sense why your feeling all emotional!
It’s also handy when your at the doctors and there asking when your last period was and how long they last for - just have a quick look at your app.
If your trying for a baby then this app is really useful to see when your ovulating and is very accurate. You can record when you’ve been ‘intimate’ which will give you a date for when it was that you conceived.
So all in all a very useful and handy app to have :)

I have never had a normal period since coming off birth control, I could never pin point when I had my last period! Now using this app makes it a whole lost easier! Not only does it pin point when you had your last period but pin points when your due it next and has a count down! Can track when your intimate last and can help you if your trying to conceive when telling you when your most likely that month! Highly recommend has a few cool things aswell

Not that great

I read the reviews and saw it had 5 stars so downloaded it and checked it out! It looked great to start with and I was excited to use and and excited that I finally didn’t have to remember a load of things in my head and also I take my phone everywhere I go so I would have this everywhere I go but if it’s marked on my calendar on my wall I can only look at home! I went onto the different things to see what I could do on the app and that’s when I noticed 3 out of I don’t know how many things were unlocked! One thing that really got to me was the moods, you had to pay £9.99 FOR THE MOODS WHICH IS ONE OF THE MOST IMPORTANT THINGS WHEN A GIRL/WOMEN IS ON HER PERIOD! As soon as I realised I had to pay for things inside the app I deleted it and went to find an app COMPLETELY FREE! I recommend this to no one who wants a completely FREE app so no in-app per chases.
