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. PRIVACY - No data collection — no analytics, no tracking, no telemetry - No network calls — the app never connects to the internet - Location stays on device — used only to keep background protection active, never transmitted - All processing happens on-device FEATURES - Choose which apps to protect - Adjustable sensitivity (2.0G – 6.0G) - Background protection via location keep-alive - Event log with location of detected incidents - Face ID or passcode unlock - Custom shield appearance - Step-by-step onboarding Free. No ads. No subscriptions. No in-app purchases.
