It’s great. No pink , no babies, no awkward sex stuff, no chat rooms, no videos, and no crazy mood evaluations. It’s just a modern electronic version of the old paper calendar tracking method. Simple and easy. ### 5/5 — A+ *2019-04-30* THANK YOU ### 1/5 — hard *2018-09-03* so i was looking for a period app that would help me figure out my days especially if i’m early or late to my period. no, this does not have ovulation which is a good thing because i do not need that, since i am only 14. it is really hard to figure out this app. i rapped the date i last had my period and it just showed up a bunch of weird calendar dates and nothing that told me what it was. it was obviously not my period because it was only 2 days. ### 4/5 — Good for young girls *2018-07-30* Finally, a period tracker a young girl can use that isn't filled with fertility and sex tracking. Thanks! I would suggest adding mood and symptom tracking as that can be important for a young girl too identify patterns. ### 5/5 — Perfect for my tween! *2018-04-13* I was looking for an app that didn’t have forums, or crazy features or ovulation/sex trackers for my girl who just started hers, and this is perfect! Thank you! ### 5/5 — Dr *2017-03-10* Thank you for designing an app for adults that isn't overwhelming with ugly graphics and wanting to know my life story ### 4/5 — Get rid of the ads!!! *2016-09-16* Love the app, simple and easy to use, but PLEASE get rid of the ads, they're super annoying! Even if you have a $2.99 upgrade or something! Just please get rid of them! Other than that, love the app :) ### 3/5 — Love! *2016-07-30* Love how simple it is. Just one press of the button especially when I have irregular periods and don't even know when my cycles are. I do wish there was an ad free option!! ### 5/5 — Very attractive; no special features *2016-07-01* I've been looking for an attractive app and I really like this one. It has a minimal design. However, it doesn't provide special features such as the "how are you feeling today" log that most of these apps have. It only has the date and does not tell you your fertile or ovulation days. That isn't a problem for me because I don't need it, but if that's something you prefer then I recommend a different app. ## Frequently asked questions about Period Flow ### How do I log a period day in Period Flow?
