Awesome app. Had it a few years now. It is pretty accurate. I would highly recommend to keep track of your cycle. I use it ever time I go to the obgyn it give the most accurate dates.

I downloaded this app to keep up with my periods and ovulation bc my body doesn’t handle birth control well and I ended up pregnant on a day it said I wasn’t ovulating just be careful if you are going by this app for ovulation bc it’s not accurate

This app has helped me plan my periods out and is pretty accurate on when my next cycle will be. I wish that it did sync or save my information if app does get accidentally deleted, but other than that it’s great. I did find out you can send an email of your data to yourself which could be helpful for doctors visits.

I don’t know where I would be without this app (probably adding more undies to the period graveyard) it is by far the most accurate app I have ever used !!

This has been a God-send for keeping up with my disabled daughter’s periods.
