Description
"Wait — where's my phone?" Let's make that heart-drop moment a thing of the past.
Phone Guardian buzzes your Apple Watch the instant the Bluetooth link to your iPhone breaks. Find My helps you locate a phone after it's lost — Phone Guardian tells you the second you leave it, so you can just turn around.
■ Perfect for moments like these
Heading out: know the second you leave your phone at the door
Cafés & restaurants: never leave it on the table when you get up
Travel & trips: avoid leaving it at hotels or airports
Trains & buses: get alerted the moment you leave it on your seat
■ Key features
Instant left-behind alert: your Watch buzzes within seconds
Distance warning: a gentle heads-up before the connection is even lost
False-alarm guard: a brief blip won't trigger it (0–10s grace)
Safe Zones: silence alerts at home or any place you choose
Ring your iPhone: find it loudly from your Watch, even in silent mode
Also a watch face: turn the monitoring screen into a digital or analog clock, with your own photo background, world clock, and corner widgets
Japanese / English: switch anytime inside the app
■ Battery friendly
Only low-energy Bluetooth and near-zero-power geofencing. No constant GPS — battery impact is minimal.
■ Privacy
No location, no analytics, nothing leaves your device. Everything stays local.
■ Before you start
Requires an iPhone on iOS 17+ paired with an Apple Watch on watchOS 9+
One-time purchase. No subscription, no ads.
Due to watchOS rules, alerts can be delayed on some models or usage patterns. If that happens, keeping Phone Guardian as your Watch face is the most reliable setup — and it doubles as your everyday clock.
Keep your iPhone safe, right there on your wrist.
