## 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.
