I have been using this app since its release in like 2017 & I absolutely love it! The little background themes & adorable little mascots are the cutest things I've seen on a Tracker app. Mine is the pretty green Christmas Tree background with the hedgehog in the Christmas outfit. 🦔 The best part is it's free, with the ads & they allow you to skip while you aren't flooded with them. It has great reminders & notifications, I love that you can customize them; I made mine silly with emojis! 5⭐ app!

Have used this app exclusively since 2012. I paid almost 5yrs ago to remove ads best decision ever. I've never lost any data and it syncs with my Google drive and is backed up. My information has Never been lost even through several different phones. Thank you for making this app and keeping it going. I would definitely recommend. May I also say I would really love a cute baby Dragon themed pet, it's probably the only thing missing for me.

Best period tracker app ever! I've tried other ones. this one is so simple and clean and accurate! there are a tiny amount of ads. can skip within a couple seconds. I dont even really notice them and they aren't often. plus you can pick pets and customize you're background and make daily notes etc.
