I love it! I have recently (start of the year) stopped the depo-povera injection so when my periods started to come back and be regular again I thought the app would be a good choice. I like that I can write notes and say how i was feeling etc and it helps me keep track of when my period should be arriving. Also good as I have never been 'regular' up until now and the app got it bang on the day I was impressed.

Great app , easy to use, you can tick as many symptoms/moods as you like. It also suggest using more graphs if its helpful to you. It tells you when your due on , fertile etc. You can also add any medication's your on aswel. It also has a pill reminder you can set for your contraceptive pill. If you take them that is! All in all I highly recommend this app!!!!

Amazing Alway correct. I like how you can choose if your reminders are discreet or not. it helps a lot. Definitely worth using and trying for yourself. Especially if you have just started and dont want to be surprised when you start again. It is just amazing because you can keep track of how long your period was the months before and you can see if you are fertile or obulating. i definitely recommend that you use this app because it is simple yet affective. You can track your flow and pill intake
