Misjudged Mischief
19 October 2025
The app itself is amazing! I'm really impressed with this, it's the first period tracking app I've used and I've loved it so far! I'm a big fan of being able to share with a partner. I wish there were themes that were less girly and more low-key and cozy. The only issue I've had so far is the ads but even then I'm not getting a crazy amount and they're usually pretty short, I'm not a fan that part of this app is closed behind a paywall but the important parts are available and free. I love it!

Love this app. I prefer the blue skin option instead of the 'pets' simply for the layout. There are so many symptoms in the list and I love that we can also customize them to a certain degree. It would be nice to have a couple of 'blanks' symptoms available to customize. Love the graphs too!! One suggestion would be to not have a line between data sets that have missing days in between🤔...I have big gaps in my tracking so sometimes the graphs lines shouldn't actually be there? Thank you!!!

I used this tracker for about 2 years (2017-2019) til I reached menopause. It is simple, pretty easy to use and it can be backed up so changing phones was not an issue. I like that you can email a report to show your dr. It has sat on my phone til now (2022), I am deleting as I no longer need this type of app, I'm leaving this review in the hopes it helps someone.
