Customer Reviews

Wish they had this when I was younger

This would have come in super handy when I was younger. I used to always have very random and irregular periods which would be heavy and last a lifetime. Now that I'm on the pill, it is much easier to know when to expect my periods, meaning this period diary is not as useful as it would have been years ago.

Having said that, the app really helps you keep track of practically every detail of your period, which is handy if you happen to visit the doctors and they ask about how your periods have been.

I also very much love the privacy settings; the app's name and logo are concealed and show no sign of what it's actually about. There's also an option to set your journal notes to 'intimate' as well as the option to password protect the app. Great little app!

What's happened?

This app was fantastic when I first got it, but for some reason the calendar has gone funny? When I select a day and add moods, notes etc to it, it puts the information onto the next date in the calendar? It never used to do this! I would have given 5 stars if it wasn't for this. It's still useful, and if you add your notes to the day before date then they will display on the right date. Not very useful though when you go back to read them because the information is attached to the wrong date. I have completely wiped and re-installed this app to see if it would fix the issue. This worked temporarily then started adding to the wrong date again, but now with the annoying fact that I have lost all my original data. Please fix this issue, this was such a good app.


I am only 12 and this app has change my life, I started my period when I was 11 and I really didn't know when it would be, but once I found out about this app, I always know when it's due. Plus, the title on my home screen is P.D, which could mean anything, that's good because I have 4 brothers who steel my phone all the time and they would looks at it of they knew what it was, also the privacy settings are good because there is a password! Overall this app is bloody sensational!!!!!!!!xxx
