Comments on 21 Days Challenge for Android

★★★★★ Sarah Rose · Jul 27, 2026

I have been mindfully reading this app's daily affirmations for over 2 years now. I love it and have come to depend on it for emotional support. 🩷

★★★★★ Dp Rocky · Jul 11, 2026

★★★★☆ Rinku Devi · Aug 9, 2026

The app is quite good you can believe the particular tasks, and all you just need to be consistent overall the app is quite good and practical.

★☆☆☆☆ দর্পন রায় · Aug 5, 2026

Your app is the world's number 1 useless app. Because, if you pay for some money, you won't show ads anymore,,, so why do you give so many ads to those of us who are middle class and use free apps? Is that a big deal? We use other apps. They are not as useless as yours. They show very few ads there. And even if they do show ads, they are good ads. Not fake ads like yours. So if you show good ads, do it, if you don't, stop it. You are a useless group.

★☆☆☆☆ Waru Jayz · Jul 13, 2026

Used this back in 2024 and it was awesome. Now can't do 1 click without an ad. It's not even worth paid subscriptions. All the apps suck now. With these horrible endless ads. You all suck
