Customer Reviews

Everything is excellent except for the design

The app is great. It has every feature you might need and it's very simple and easy to use. I just take issue with one thing: design. All of the skins look really childish (like a Disney Princess app or something) and they are not at all discreet (which I think is something we'd all appreciate when updating it with intimidate details in public spaces). I wish the developers would go for something much more simple and inconspicuous (no flowers and flowers patterns with extremely bright colours everywhere), more like "Cycles". That being said, I do think it's a great app, would recommend it to anyone who likes/needs to keep tracks of her cycles with some care for whatever reason and I'll continue to use it.

Excellent! Can't live without it!

I started using this app back in 2011.
I'd noticed my periods had become irregular and wanted to keep track. In 2012 I was diagnosed with PCOS and with thanks to PD I was able to give accurate dates to my doctor and show how late and irregular my periods were!
I use it every month and I truly couldn't be without it now!
It's helpful to see predictions for periods (which helps with holidays) and also predications for fertility and ovulation (which will come in handy when my husband and I try for a family this year!)
The only thing I'm disappointed with is the data isn't saved anywhere. It's only saved to the phone, so when I got a new phone the end of last year I lost all my data 😭
Otherwise I can't recommend it enough.

Great app!

If you're rubbish at remembering to note when you have your periods ( like me!), then this is the app for you! I've been using it for about a year now & have found it really useful & (more importantly) accurate! It plots your periods & gives you your next due date based on the information you input & it's possible to note your moods & weight etc alongside your period dates too. I think it's great...& it's free, so why not try it?!
