Snatch Guard - App Lock

Snatch Guard detects the moment someone grabs your phone and instantly locks your sensitive apps — banking, messaging, photos, notes — with a system-level shield that can't be dismissed without your Face ID or passcode.

HOW IT WORKS

- Detects the grab — the built-in accelerometer senses the sudden jerk when someone snatches your phone.
- Locks your apps instantly — system-level shields appear over your selected apps within milliseconds.
- Only you can unlock — Face ID or device passcode required to remove shields.
- Works in background — protection stays active even while you're using other apps.
- Tamper resistant — shields stay active even if the app is force-closed. With Screen Time passcode enabled, the app can't be deleted or bypassed.

WHY SNATCH GUARD?

In London alone, over 117,000 phones were stolen in 2024. Thieves target unlocked phones — they grab and run, then immediately access your bank accounts, messages, and photos.

Apple's Stolen Device Protection only delays password changes — it doesn't protect the content of an unlocked phone. The "Require Face ID" feature only works at app launch — if the app is already open when snatched, there's no protection.

Snatch Guard fills this gap.

FALSE POSITIVES?

If you run for a bus and the shield activates, simply open Snatch Guard, authenticate with Face ID, and remove the shield. Takes 3 seconds. You can also adjust sensitivity in Settings.
