Omamori Anti-Loss

Your Apple Watch buzzes when you leave your iPhone behind. It stays quiet while either device is charging, or during the quiet hours you set. Buy once, 7-day trial.

Omamori watches the Bluetooth link between your Apple Watch and iPhone — a simple guard against leaving your phone behind.

When the two move apart and the link drops, your Apple Watch alerts you with a vibration and a notification, so you notice a left-behind or lifted iPhone within seconds to a dozen seconds.

An honest, active guard — not magic Omamori is an active, connection-based guard. It does not promise an instant alarm while running in the background 24/7. No exaggerated claims.

Features • Proximity alarm — the Watch vibrates and notifies when the link to your iPhone drops • Adjustable grace period — tune how long a disconnection must last before it alarms, to avoid false alarms • Choose after an alarm — when it goes off, pick "keep guarding" or "stop" right on your wrist • Ring your iPhone — make it sound from your Watch to find it around the house, even on silent or while locked • Guards only your own iPhone — other people's devices are ignored
