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 don't like Apps that let me input my details and let me think that it's for free. Then the minute I think I can start tracking, they bring the payment page. Not everyone can afford to pay so just make it clear from the get go without giving others false hope. For those that can pay it's a really nicely set up App.

Hello! Period Calendar has a premium version, which is a way for us to keep the app free and support its further development. All paid features are optional and the offer screen can be turned off in the top part of the screen. No purchases are required to use the app. Best regards, Lisa
