Your Phone's Personal Guardian
Get instant Apple Watch alerts when someone moves your iPhone. Simple, focused protection that works in the background.

Smart motion detection that adapts to different types of movement
Level 1: Nudge
Gentle haptic on your watch when someone touches or slightly moves your phone. Subtle awareness without alarm.
Level 2: Pickup
Strong watch vibration when your phone is lifted or tilted. Someone's picking it up - time to check.
