Your phone steals hours every day. Zentry helps you take them back. Pick the apps that pull you in, then let Zentry put a calm wall in front of them — for a quick focus session or every day on a schedule. When you try to open a blocked app, you see Zen, your focus buddy, instead of the feed. FOCUS IN ONE TAP Start a session from 15 minutes to 2 hours. Your apps stay blocked even when Zentry is closed, and you get a notification when you're done. BLOCK ON A SCHEDULE Create groups like Work, Study or Bedtime and set when they lock — 9 to 5, every evening, or always on. Zentry handles the rest automatically. A CALM SCREEN, NOT THE FEED Blocked apps show a gentle reminder of how often you've held back today. Need a moment? Open an app for 5 minutes and get right back on track. WATCH YOUR TIME COME BACK Insights show your focus time, best days and streaks. Build the habit one day at a time. MEET ZEN Zen sleeps, cheers, gets overwhelmed by notifications and celebrates every finished session with you. PRIVATE BY DESIGN Zentry uses Apple's Screen Time framework. Your app list and usage never leave your iPhone. No ads. 12 LANGUAGES English, Deutsch, Français, Italiano, Español, Nederlands, Suomi, Slovenčina, Slovenščina, Eesti, Shqip, Русский.
