The Church of Scientology of Period Tracking Apps

Once you join Flo, there is no going back. It changes you in ways completely unimaginable. This is my fourth period tracking app, yet this is the only one which ACCURATELY tracks my periods. Originally, you can set average cycle lengths and period lengths but as you use the app more, Flo uses the data stored to improve predictions. It has pill reminders and reminders for when the period will start. Literally life-changing. The design is nice, and Flo has multiple aesthetically pleasing backgrounds from which to pick. Also, if you don't want everyone on your tracking app, there are passwords to protect you!!!!! One of the best features, though, is the ability to log symptoms. Flo, the wonderful woman that she is, will link you to accessible information to help you better understand these symptoms and how to treat them. Surveys also serve this purpose, acting as a free period game, SO FUN.

As you can see, I clearly love Flo. There is only one thing I wish for that would make her the perfect woman. I wish for the ability to Flo with my friends. I recently converted a friend to Flo and we were so disappointed that we couldn't Flo together. Imagine the possibilities, including but not limited to, knowing who else is Floing and knowing who has the tampons.

Flo, although I have this one criticism, know that I still love you and would stain all my nice underwear without you.

Total Game Changer

I am obsessed with this app and have told all of my female friends about it. Never before have I had a health app that I actually stuck with and was not annoyed to use every day. Quite the opposite here, I look forward to logging symptoms each day as the app is so intuitive and the interface is incredibly pleasing. I rated 4 stars because I echo a lot of the other reviews in that I would love to see more graphs and data based on cravings, sex drive and especially mood. I have been using this app in conjunction with monitoring fluctuations in my mental health during my cycle, so any new features that could assist with this would be incredible. A more in-depth ability to measure bowel movements throughout the cycle would be useful as well as I have endometriosis, which occasionally can cause issues in that department that are important to track. Looking forward to see where the future of this app goes!

Minor fix for the future

I really like this app. It is a good way to track things and overall, is well built and designed. Their are just a few things that I find to be somewhat of a nuisance. One of them is logging your sleep. The feature of having a stop watch of sorts so you don't have to keep track of what time you go to bed and wake up. The only issue is that you can't start the timer the "day" before you sleep. In other words the start and stop time is completely useless unless you start the timer at or after midnight, which counts as the next day. It would be nice if I could start the timer before that, hence using the feature all the time instead of only the times I feel like staying up late on a weekend. Another quick thing is that I think their should be more variety for the exercise tracker. Besides that, great app.
