BagWatch turns your iPhone into a smart bag alarm. Place your phone inside your bag, tap Start Alarm, and enjoy your day — if someone tries to steal your bag, a loud siren fires quickly to scare them off and alert people nearby. Designed for iPhone — place your iPhone inside your bag to use BagWatch. (Runs on iPad in iPhone compatibility mode only.) HOW IT WORKS • Tap Start Alarm and wait 15 seconds while you get ready • Lock your screen and place your iPhone near the top of your bag • BagWatch monitors motion in the background • If your bag is lifted, carried away, or snatched, the alarm sounds • Unlock your phone and tap Turn Off to stop the siren LOUD SIREN + YOUR VOICE • Choose from multiple siren sounds • Record your own voice alert (for example: “Stop! That’s my bag!”) • Voice clips stay on your device — private and local PRIVACY FIRST • No account required • No cloud upload of motion data or voice recordings • No ads, no tracking, no analytics • Sensor data is processed on your device in real time • Microphone used only if you choose to record a voice alert SUBSCRIPTION • Start with a 7-day free trial — no payment required upfront • After the trial, continue with an annual auto-renewable subscription (price shown in the app; localized by the App Store) • Renews automatically each year unless you cancel at least 24 hours before the end of the current billing period • Manage or cancel anytime in iPhone Settings → Apple ID → Subscriptions • Your subscription syncs across devices signed in with the same Apple ID IMPORTANT BagWatch is a theft deterrent, not insurance and not a connection to police or emergency services. Stay aware of your belongings and use the alarm as an extra layer of protection. Perfect for cafés, study sessions, beach trips, co-working spaces, and anywhere you need to step away for a moment.
