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. No personal data is sent outside.

You got home, dropped onto the couch, and opened your feed "just for a second." Forty minutes later you're still scrolling. Again. That's not a discipline problem. That's what your phone is designed to do. NoScrollHome is a different kind of app. With NoScrollHome Pro, at a place and time you choose — like home, in the evening — it locks the apps that pull you in: social media, video, mail, browsers, games. They stay locked while you're there, so the moment you walk in the door, the pull is gone. App blocking and the full feature set described below require a NoScrollHome Pro subscription. A 7-day free trial is available with the Yearly plan. Without NoScrollHome Pro, you can explore the onboarding, but app blocking is disabled. When you leave home, or the time window ends, the lock lifts. Your phone is yours again, until the next time you come home. It's not about willpower. Blockers ask you to resist a button that's always one tap away. NoScrollHome makes the button disappear where and when it matters most — automatically, even if the app is force-quit — so there's nothing left to resist. How it works 1. Pick the apps that pull you in. 2. Set your home and the hours you want them gone. 3. Arrive home during that window, and they lock themselves. 4. See your home zone on a map, how many apps are blocked, and the nights you stayed off. Everything runs on your device. Your location and your app choices never leave your phone. How a day might look with NoScrollHome Pro 6:30 PM. You get home. Social apps lock on their own — no button to press, no settings to toggle. Dinner without a screen in your hand. 9:00 PM. Still locked. The evening is yours: read, talk, rest. If you genuinely need out, one emergency unlock is there — but you'll think twice. 7:00 AM. You leave for the day. The lock lifts on its own. Your phone is fully yours again, until tonight. A note on what we don't do No social feed. No friends leaderboard. No notifications begging you to come back. Nothing about NoScrollHome tries to keep you on your phone — the whole point is the opposite. Subscription details NoScrollHome Pro is required to use app blocking and the full feature set. A 7-day free trial is available with the Yearly plan. After the trial, the Yearly plan is billed annually at the price shown on the subscription screen. The Monthly plan is billed each month at the displayed monthly price. The Lifetime option is a one-time payment with no recurring charges. Your Yearly subscription renews automatically at the end of each 12-month period unless you cancel at least 24 hours before the trial or current period ends. Canceling stops future renewals; you keep access through the end of the period you've paid for. Subscriptions are managed in your App Store account. Deleting the app does not cancel your subscription. Terms of Use (EULA): https://zen-first.com/terms Privacy Policy: https://zen-first.com/privacy

Verdict
The clearest difference is in-app purchases: ZenLock at none against Ultimate Focus's 4. ZenLock also leads on update cadence (every 5 days vs every 10 days). On price, ads, device support and iOS requirement there is nothing between them.
