Customer Reviews

Good way to keep track.

I like that this tracks my steps, my symptoms, fertility, and of course my cycle. One thing I think would be helpful is maybe adding a percentage of pregnancy prediction if you're past your normal period window? Although I could see this making some people anxious lol. As far as accuracy with timing my cycle, it's usually within a 4-5 days of being accurate.

Fantastic Display!

I just love they way the whole layout fits together perfectly. This app is great for tracking my cycle and I love getting some help and facts when I don't know what's going on, it would be great though if you could put the intensity of your symptoms somehow so you could get a good feeling of what is normal and what isn't.


Amaaazing app keeps u on track!!!
