I have been using this app for YEARS! (Approximately 5-6). It is fantastic and helpful, especially when I go to my OBGYN for a check-up because I can log my symptoms, gauge their severity, and share these findings with my doctor. There is even an area where you can take notes. I use those sporadically to document my experiences, primarily to note drastic changes from previous months. Also, the free version is effective, and there is not a bombardment of ads!! I highly recommend it!

It's pretty good! Does what you'd expect from a period tracker. Firstly I wish for the ability to add custom symptoms— there are a few things I wish to track that aren't an option! Secondly I'd love a one time purchase for premium, I'd like to use a bunch of the premium things but I can't afford subscriptions— $24 a year isn't bad for one app but when every app wants a subscription it adds up so quickly

i love this app, I've been using it for probably a year now. i love all the options for symptoms and such so i can keep track of my odd cycles more thoroughly. however, the app kinda forces on you a "determined" section of time when your cycle or ovulation is happening. i have VERY irregular cycles and very irregular ovulation cycles, and i can't actually choose when ovulation is happening and instead i have to write it in the notes, which can be confusing. other than that, a great app.

Hello! Thank you for your feedback! While we don’t currently have a dedicated feature for irregular cycles, we appreciate your input. You can adjust the ovulation window manually - feel free to email us at feedback@period-tracker.com for detailed steps on how to do that. Best regards, Lisa
