I really like this app and have been using it for 5 years now! Its simplicity and efficiency is so great and I love that it's free with the ads not being so invasive (was great as a teenager who didn't have money and even now as a college student still figuring life out). The one thing I'd love to see is the option to pair the app with a partner so they can get insights to the cycle dates and symptoms you log, and maybe even leave little notes. For me that'd make the app a perfect 10/10!

I am incredibly suprised by the access available on the app when it is a free app. The ad removal is really small. there is a paid for version. I haven't done that yet but to give u an idea of what not to do. I recently purchased a brand thermometer that said it connected with Bluetooth to their app... 1 it didn't and 2 everything was locked in the app and it was a complete waste of time and money. I am so happy I found this app.

I have been using this app for over a year and I absolutely love it. It's simple and have all the functions I need without having too much. What keeps me from giving it a 5 star is one little flaw. When you click to see the individual days and input your notes, on the top shows the dates of the supposed day. However the date is wrong and when you try to click the date next to it, it doesn't bring you to the next day, but brings you to another previous date instead.
