Didn’t expect much, but this app really helped me stop wasting time on YouTube during work. The blocking sessions and timers keep me focused - I actually get things done now instead of falling into endless scrolling. Feels good to finally be in control. Thanks.

I didn’t think an app could have such an impact on my habits. Within a couple of weeks, I found myself reaching for my phone less out of boredom. Everything is clean, simple, and easy to use

I downloaded this app on a friend’s recommendation — honestly wasn’t expecting much. But over time, I started noticing real changes in how I use my phone. I’m more intentional now and no longer open random apps out of reflex.

I used to open social media without even realizing it. Quark helped me become more intentional with how I use my phone. It’s honestly changed my workdays - I get more done and feel less drained
