Easiest to use

I have tried so many different period tracking apps and this is by far the simplest, which is what I need.

Two issues.
One, I wish I would stop asking me to backup my data. I don’t want to backup and it’s always in the way.

Second, I wish the data would share to the Heath App on my phone to then flow through to other health related apps. It’s why I keep trying other apps because they flow through, however the others are so complicated I keep coming back.

Thank you for your positive review! Can you please email us at so we can address your backup issue? Your feature request has been noted and I will discuss with my team.

The predictions need a little tweaking

The predictions are sometimes inaccurate if you have a temp spike for some reason. I have been measuring my basal temperature and logging it. On Day 6 of my last cycle I had a low grade fever and so my temp spiked, and for the whole rest of my cycle it said “you’ve already ovulated” even though my basal temperature went back down to a steady temp. I’d say most women don’t ovulate on day 6, and so there should be more to the algorithm than just a spike in temperature. Basically it’s just a way for me to log it, but I still have to use my own common sense and can’t rely on the predictions.

Hi Kohlerhuset. That's really useful feedback and we greatly appreciate it! We'll definitely see if we can filter things like that out.

10 years using this app.

I just wanted to drop a line and say thanks to the creator of this app. I started tracking my period in my early 20s and I wished I had done it sooner. It's game changing. It allows you to recognize pre/post period symptoms, truly get to know your body, plan ahead of big days and big decisions, as well as enjoying sex responsibly. I wouldn't have been able to do this without this app. Thank you!

So good to hear about your great experience with our app! Thank you for sharing your feedback!
