ZenLock is an App Blocking App that *forcefully* stops the apps you overuse. ◆ Simple Flow ・Select addictive apps like YouTube, TikTok, Instagram, X, or games to block ・When you really need them, choose a temporary unlock time (15/30/60 minutes) → Unlocking requires passing a randomly generated 10-character challenge →→ This extra step makes you ask: “Do I really want this app badly enough to type it out?” ・Even while using the app, once the chosen time is up, it will be blocked again automatically → No more “I only meant 15 minutes on YouTube, but suddenly it’s been an hour…” ◆ Perfect for people who: ・Spend too much time on social media or video apps ・Struggle to stay focused on study or work because of their phone ・Lose sleep from late-night endless scrolling and regret it the next day ZenLock helps you change habits without relying on willpower. It’s ideal for anyone who feels guilty about wasted time, wants to secure focus for study, work, or side projects, or simply start a digital detox. ◆ Safe & Private ZenLock runs entirely on-device using iOS system features.
