Comments on Check Calendar - Habit Tracker for Android
★★★★★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
★★★★★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.
★★★★★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.

The fact that they LOCK YOU OUT of using the app after a week to FORCE you to pay for the premium version is disgusting. It's just an app to check the days of the calendar, I ain't giving you ONE SINGLE CENT for such a simple app my guy. I'll just keep browsing over the store and look for an actual free one. God this is one of the most nauseating cash grabs I've ever seen. It doesn't even deserve one star.

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.
