I think this is a great app! I like being able to log my periods and if they were more regular I could set an alert to notify me of when I was going to start. I don't use the ovulation thing so I can't speak to its performance but it looks like it would be very helpful. Also I can log in certain symptoms I'm having that day. This app is actually very helpful. I highly recommend it. Plus it's free and you only have one small ad and you can basically just X it out.

I've been using this app for a while and it's very good. it's pretty accurate for the most part, i get a lot of irregular periods so not many trackers know what to do but this one is cool. there are lots of options for symptom tracking and stuff. one recommendation i have is to add a tampon reminder that reminds you to change them, and there could be a button to say "I've put a tampon in" that turns it on. just a suggestion though. edit: stopped using the app because of privacy concerns :\

Easy to use and about 90% accurate with period predictions. I love the "notes" section where I can journal how my day went and what may have caused any mood swings or lack of energy. Good app for free! Highly recommend! EDIT: OK, all I just went back and was going to start keeping track of my weight again bc it has fluctuated a lot in the past year and I was am hoping to find a reason along with my doctor since I've made no lifestyle/diet changes but there is nowhere to enter weight now. Help?

Hi. To do this, click "add symptoms". Then in the upper right corner click on the pencil (edit) and move the checkbox next to "weight". Then enter your weight data.
