I think the people saying "this is the best app ever but I hate the ads" need to just pay for it instead of expecting something for free. Especially while you're admitting that it's the best tracker you've used. I use it every day and it's very inexpensive to remove the ads. I'd like the developers to allow us to change the cover line on the temperature chart, as its frozen at 36.7c so doesn't actually do anything. You should also let us change ovulation date predictions.

Hi, thanks for your feedback. You can edit the ovulation day by adding a positive ovulation test(Add Note -> Tests/Monitors -> Ovulation). We will keep trying to optimize our app in these aspects. Hope to give you a better user experience. For any issues, please feel free to contact us at periodtrackerfeedback@gmail.com. Thanks!

Hands down the best period tracker app! Very customisable! Love the free themes and the colour scheme. Most of the other apps have cringe-worthy cartoons etc, as if aimed at 5 year olds... This one has 'pets' but you have the option to remove them. I love the simple layout, plus the calendar has cycle days which is important to me! The only improvement i can think of is the option to have more than 1 notification for your period, e.g. a reminder a few days early, then another one the day before.

I have been with this app since 2019, and I have zero complaints. I chose this app because it's free , cute with the animals, and because I stopped taking the pill. I got to know my body better, and my period arrived when the calendar told me. I wouldn't mind having an option where I can write a note. Love the graphics and the simplicity. Thank you for teaching me how to understand my body better.
