The Mira app is fantastic. It gives you your fertility levels and even a number! It could not be easier or clearer than this. I've been using it for over 1 month now and I can't be without it anymore.

With Mira, I found out that my ovulation was much later in my cycle than most of the apps predicted. Really love it so far!

It’s great to see how different hormones change throughout the cycle and get much more accurate results than your usual app-only cycle predictions.

I've always had irregular cycles, and the Mira app is already helping me understand some aspects of my cycle I've never considered before.

The app is so comprehensive, and I do enjoy entering my data, unlike other period tracking apps I use.
