Easy to use and happy with what I need it for.

I’m sure that I don’t use this app to its full capacity, however, to help keep track of where I’m at in my cycle, when to expect my period and also future predictions! Super helpful when planning holidays and Gynae check-ups! I also read a lot about women’s health and this app helps me to easily see where I am at in my cycle and compare how I am feeling (physically, mentally and emotionally) with what I read about those stages in my cycle. I’m lucky that I have a regular cycle and no menstrual health issues that I’m aware of - I imagine that this app would be so helpful to track symptoms for those that do and be able to give their health advisors a clearer picture of what they go through. The deco of the app is a bit childish but other alternatives also seem to do the whole pink-flower-thing. It doesn’t bother me - I like being able to protect access to the app with a passcode too 👌🏻

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.

Very useful Ap

I find this very useful to monitor symptoms and mood swings etc as well as being able to see how many days you have left and predicted future dates which if you have a holiday planned, can be a life saver. I do agree that the graphics etc make it look very child like but get that this is maybe something aimed more at teenage girls but it’s also good for us older ones or for monitoring periods and length when entering menopause etc so an update on this would be perfect 😊
