TapLock turns a physical NFC card into the only key that unlocks your apps. Tap your card to lock your iPhone's distracting apps behind a Screen Time shield. To get them back, you have to physically tap the card again. The card has to be in your hand. There are no shortcuts. HOW IT WORKS Choose which apps to block, then tap "Lock Now" Apps stay blocked until you tap your registered NFC card to the top of your phone Need a break? Pause the session and it picks up right where you left off Set a timer to auto-unlock after a focus session ends WHAT CARDS WORK Any NFC card you already carry: transit cards, hotel keys, student IDs, office keycards, or cheap NFC stickers. If your iPhone can read it, TapLock can use it. FEATURES NFC card unlock, tap to lock, tap to unlock Timed locks with auto-unlock countdown Pause and resume a session without losing your remaining time Custom blocking profiles, block specific apps or allow only a selected few Multiple cards supported, each with its own name Block app deletion while locked so you can't cheat by uninstalling Session stats, see your total focus time and how long your last session ran Live Activity and Dynamic Island timer visible from your lock screen Your cards and settings sync across your devices via iCloud Remote Key, unlock a family iPad or second iPhone by tapping your card on your own iPhone Native iPad app with a landscape layout REMOTE KEY AND IPAD Lock a family iPad or a second iPhone, then open it by tapping your card on your own iPhone. Both devices just need the same Apple ID. iPads have no NFC reader, so they pair as a kept device and are always opened from your iPhone. EMERGENCY ACCESS A 6-digit PIN is available if you lose your card. It works, but it is deliberately slow, so you will want to keep your card nearby. TapLock does not replace your iPhone's lock screen. It uses Apple's Screen Time framework to shield apps while your phone stays accessible for calls and emergencies. Free 7-day trial. One-time purchase. No subscription, ever. Terms of Use: https://www.aimakecoolstuff.com/legal/taplock/terms Privacy Policy: https://www.aimakecoolstuff.com/legal/taplock/privacy

Verdict
The clearest difference is in-app purchases: Lecture Viewer at none against TapLock's 2. Lecture Viewer also leads on iOS requirement (13.0 vs 17.0). TapLock's advantage is update cadence (every 4 days vs every 11 days). On price, ads and device support there is nothing between them.
