Your phone locks the apps you choose. Your body opens them. Pick the apps that eat your day. When your minutes run out, MonkeyLock locks them — really locks them, using Apple's Screen Time system. To open them again, you move: push-ups, squats, sit-ups, lunges, jump rope. Your camera counts the reps on device. Every rep buys minutes back. That's the whole idea. No willpower required, because willpower is the thing that keeps failing. FREE TO USE The wall works free. Block as many apps as you like, earn as many minutes as you like, keep your streak, keep your history. There is no trial timer and nothing expires. HOW IT WORKS • Choose the apps to put behind the wall • When your balance hits zero, they lock • Do the reps — your camera counts them, nothing is recorded or uploaded • Minutes go back in the bank and your apps open • Brain games and Apple Health steps earn a little on the side THE WALL IS HONEST ABOUT ITSELF An app you add to the wall goes on instantly. Taking one off waits until the next morning. That delay is deliberate: it means the wall does not move at the exact moment you most want it to. And when you genuinely need in — an airport, a wedding, a message that will not wait — Break Glass gives you five minutes for a ten-second hold. Three a day. No reps, no cost, nothing owed tomorrow. A blocker that only ever says no is a blocker people delete. BUILT TO STAY OUT OF YOUR WAY • Everything happens on your device. No account, no sign-up, no servers. • Camera frames are processed live and thrown away. Nothing is saved or sent. • No ads. No tracking. WHAT YOU GET FOR SHOWING UP Ranks, streaks with a couple of mercy days, and a Sunday page that shows the week you actually had — how many days the wall held, and what changed. Requires iPhone with iOS 17 or later. Screen Time permission is needed for blocking to work; MonkeyLock asks for it during setup and explains why.
DoomShield

Stop losing hours to the scroll. DoomShield locks the apps that hijack your attention—Instagram, TikTok, X, and more—until you earn them back with real push-ups. HOW IT WORKS 1. Pick the apps that drain you. 2. Open one and DoomShield's shield blocks it. 3. Do your push-ups—the AI camera counts every rep. 4. Earn a timed unlock. When it's up, the shield comes back. It's a simple trade: move your body, get your time. No willpower required—just a rule you can't swipe away. REAL, UN-BYPASSABLE BLOCKING DoomShield uses Apple's Screen Time technology to block apps at the system level. This isn't a timer you can dismiss—it's a real shield. EARN IT WITH EFFORT Turn doomscrolling into reps. Every unlock costs a few push-ups, so the more you reach for your phone, the stronger you get. SQUAD: STREAKS WITH FRIENDS Add friends, build daily streaks, and keep each other honest. Nudge your squad when they slack—accountability is the cheat code. TRACK YOUR PROGRESS See your push-ups, unlocks, and streaks over time. Watch wasted hours turn into reps. DOOMSHIELD PRO Upgrade for unlimited blocked apps, unlimited daily unlocks, custom rep and session targets, and full stats. Beat the doomscroll. Build the habit. Get your time back—one rep at a time.

Verdict
The clearest difference is ads: MonkeyLock at none against DoomShield's shown. DoomShield's advantage is update cadence (every 4 days vs every 10 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
