Comments on Check Calendar - Habit Tracker for Android
★★★★★Erik Andresen· Mar 15, 2026
I was looking for a super simple app where I can mark days on a calendar for my training schedule. This is great for my needs.
★★★★★Joyce Kamanga· Mar 13, 2026
It's simple and easy to use. I love it. I purchased the full version. I love that I can see my progress on the data feedback section, and I customize the icons with emojis for each tab I open. One improvement I would love to see is a drop-down option for multiple tabs when you first open the app, so you can see all your tabs.

★★★★★Devin· Feb 5, 2026
I use it to keep track on my daily workouts, and honestly is kinda serves as a good motivation to see those checkmarks at the end of each month, encouraging me to keep going. Great app overall
★☆☆☆☆Chesre' Rampal· Apr 1, 2026
A check calendar app? That you have to pay to use? 129.99 fee? Are you taking the piss?
★☆☆☆☆Ann· Jul 3, 2026
App starts with a 7-day free trial. After that ends the app forces you to buy their premium subscription, or you can't use the app.
★★☆☆☆LENRED ROIE OCAMPO· Mar 17, 2026
Getting some bugs sometimes the checked day did not reflect the check icon, or it does not show it is checked already, but it is already checked.
★☆☆☆☆Kara Ka· Apr 9, 2026
It didn't have a free version. Last only for a week. Then I have to purchase it 🙄
