Zentra: App Blocker & Focus

Zentra is an app blocker with Strict Mode for deep focus. Block apps, block websites, and track screen time with goals, streaks, and insights that help you stay focused.

You pick up your phone to check one thing and twenty minutes later you are still scrolling. Zentra gives your attention somewhere to hide with boundaries that actually hold.
