About

ShakeLock

Read full description

You unlock your phone. Before you know it, 30 minutes of TikTok are gone. ShakeLock adds one tiny physical hurdle — a shake — to every app that hooks you. Just enough to break the autopilot. WHO IT'S FOR - People who lose hours to YouTube, Reels, TikTok, X - Students and workers who need real focus, not just willpower - Anyone who tried Screen Time and watched themselves tap "Ignore Limit" - Digital detox, dopamine reset, attention training HOW IT WORKS 1. Pick the apps you want to limit (YouTube, X, Instagram, TikTok, games, anything) 2. When you tap them, a "Locked" shield appears instead 3. Tap the notification, then shake your phone to unlock 4. Keep shaking — the ring fills up. Stop, and it drains. Continuous energy, not a step counter. 5. Hit 100% and the app finally opens WHAT MAKES IT WORK - 3 difficulty levels (Easy / Normal / Hard) — tune shake intensity, fill time, and drain rate to your own resistance - After unlocking, the app stays open for your chosen cooldown (e.g., 5 min). Auto-relocks when time's up. - Built on iOS Screen Time / Family Controls — the lock is real, not a screen overlay - Optional: watch a rewarded ad to skip the shake (still better than thoughtless taps) - Interstitial every 3rd unlock keeps the app free PREMIUM (monthly subscription) - No ads - "Watch ad to open instantly" — unlimited - "Temporary unlock from Settings" — unlimited - "Delete penalty ads" skipped (you can remove locked apps without watching 3 rewarded ads) PRIVACY - Uses Family Controls, Notifications, Shortcuts permissions - No personally identifying data collected - Full policy linked in-app This isn't another willpower app. It's a 1-second physical interruption that lets your conscious self catch up to your thumb. Try it for a day — you'll feel the difference. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

The clearest difference is ads: Envelope Printer Labels at none against ShakeLock's shown. Envelope Printer Labels also leads on device support (3 vs 1) and iOS requirement (16.0 vs 18.0). ShakeLock's advantage is update cadence (every 3 days vs fortnightly). On price and in-app purchases there is nothing between them.
