At-a-glance representation of the current cycle.

Ratings and Reviews

Poor functioning

Juniper somewhere

I opened the app and started to fill out the days of my cycle, and it got stuck on my keypad. I'd leave a review for the rest of the app but I'm unable to access it due to the initial glitch.

Waste of money

Poorly functioning with limited capacity.



I love this period tracker app! It has a discreet, elegant design and is very easy to use. It also includes lunar fertility. Exactly what I was looking for!
