For me the best app

I have 3 apps I use and this one is the best. I subscribed for another app for another year and it was quite expansive. Only later I read book Taking charge of your fertility and discover this app. I can not recommend this enough. The app I paid for whole year is based purely on temperature so unless you have super regular period this will not be able to predict any changes to your regular patent.

This app on other hand has everything. It is able to tell you your fertility window is approaching even if it is different than other months. It can help you identify any issues with your fertility. There is very useful Community section where you can ask questions and get a prompt answer.
I find it much more reliable. However the prerequisite for this app is knowledge of FAM.

Frustratingly slow

I don’t know what the problem is with this app as I’ve been using it a while with no problems, but in recent weeks it’s become very slow to log in and update information. If I try to enter my data without waiting to be logged in I end up with a duplicate day and the whole calendar needs to be cleaned. Today I told it I had started a new cycle and it just cut me off in the middle of entering my temperature to spend several minutes updating. It’s supposed to be quick and easy but there is more and more waiting around these days.

That said, I do find the charts on the whole really helpful and easy to read. I wish it were possible to adjust the peak line and cover line though as sometimes I know the automatic one is wrong!


Great app, easy to use

Considering it’s free, this app is really fantastic. I’ve not used others but this one is so easy to use and allows you to complete loads of detailed information. Reasons for 4 rather than 5: the logging in can sometimes be a little funny, and I occasionally need to reboot the app; UX could be slightly better - moving between different functions (e.g. charts from different cycles. But definitely far from deal-breakers
