Been a user for YEARS and I still love it.

This app is great and Ive relied on this to track my cycles for years
The thing I love most about this app is that the upgrade is actually optional. If you want all the extra stuff, go for it but its not one of those apps where the free version is barely anything.
Ive tried other tracking apps and all of them are complicated and weird. This app is the only true OG period tracker!!
