LockIn
Read full descriptionHide full description
The lock actually locks. LockIn blocks the apps you choose — and the only way back in is the key YOU picked. Not a toggle you can flip off. A real key: • An NFC tag stuck on your fridge, your desk, your gym locker • A QR code in your wallet (or the barcode on your gym pass) • Your fitness goal — close your rings, hit your steps, earn your apps back • A person you trust who approves early exits • A timer or weekly schedule that holds until it's done • Or plain one-tap blocking when you just need a nudge Every focus session builds something: your Realm — an island that grows piece by piece with every session you finish. Miss a day and it weathers. Keep showing up and it becomes somewhere you don't want to burn down. WHY IT WORKS LockIn is a commitment device. The friction is the feature: when quitting means walking to the fridge to scan a tag, you mostly don't quit. • Smart Breaks — pause for a few minutes without ending the session; blocking resumes automatically, even if you force-quit the app • Strict Mode — apps stay blocked even if you try to delete LockIn • 3 emergency unlocks per month. Genuine emergencies only. That's the point. • Weekly schedules that arm themselves — even when the app is closed • Live Activity on your Lock Screen and Dynamic Island • Siri & Shortcuts: "Start LockIn" from your Action Button PRIVATE BY DESIGN Your app selections, health data, and location never leave your iPhone. No accounts. No analytics. No ads. (Full policy inside the app.) Lock in. Build your realm.

Verdict
The clearest difference is in-app purchases: LockIn at none against Microsoft Outlook's 4. LockIn also leads on ads (none vs shown) and iOS requirement (17.0 vs 26.0). Microsoft Outlook's advantage is chart position (#13 vs unranked) and device support (3 vs 1). On price and update cadence there is nothing between them.
