I adore this app. It helped me jeep track when I was having issues and no one believed me when I told them I was having 3 periods a month. Turned out it was my birth control. Now I'm doing a natural birth control where you test you lady parts and this app just helps keep me on track.

Love this app. I started using it to track my cycle after i went off the pill because period was really irregular for a while. But now it's great to just record everything :) accurate timing as well.

Really disappointed. Used this app for years and always used the automatic calculation for my cycle. It was great and then I got pregnant. Since then it has gone down hill. I tried deleting my record, using the manual cycle etc but still, every single month with out fail since around December 2016 it has caused me to think that my period was late. -_- apparently I'm two weeks late when I literally had my period three weeks ago? Great app if it can actually calculate your cycle accurately. I'm gutted to say I'm deleting this app and searching for a more accurate one.

I don't like giving bad reviews but "pay to be ad free for only 30 days" is a total deal breaker. That's shady and crappy for the user. Overshadows the cool things about this app. Uninstalled.

This does a great job of keeping me on track with my period through effective notifications that are not repetitive. I only wish they would analyze data closely. For example, if there is some discrepancy or irregularity in the data you've entered, the app should send a brief notice suggesting there might be a problem and offer resources and possible solutions to the user.
