probably the best app I've ever had. not an understatement. so I've had this app for about 4 years, and it's the only period app I've ever used. at first I didn't want to track my period, but this makes it easy! it's calculations are generally accurate and I love the way that it adapts as you do too. so many amazing features that I love. keep up the good work. ❤️❤️❤️

I am Furious! I have been using this calendar for years probably at least five or more years. I knew my period was coming soon and I went to track something on my calendar and couldn't find the app. I don't know how it got deleted from my phone but it did. when I re-downloaded the app to my phone and logged in every single bit of my data is completely gone. everything!

This is an amazing app!! earned the five stars all the way! not pushy about getting premium and not stingy on what you have access to without it at all! You can track your period and what phase you're currently in, and it will tell you all about what is expected during that phase! you have mood logging options, helpful notifications that tell you when you're supposed to start, helping you drink water, etc. plus a cute theme and a privacy lock!
