WatchDog Key

Never truly unattended. WatchDog Key turns your iPhone into the remote for Rex, the watchdog living on your Mac. Step away from your laptop in a café, library, or co-working space and let Rex keep an eye on it. The moment something happens, you'll know. — What WatchDog Key does — Instant alerts. The second Rex detects tampering on your Mac, a push notification reaches your iPhone. No delay, no guesswork. Remote arm and disarm. Your phone is the key. Arm Rex before you walk away, disarm the moment you sit back down, all from the lock screen. Bluetooth proximity. Forget to arm it? Rex does it for you. WatchDog Key automatically arms your Mac when you walk away and disarms it when you return. Live protection status. See at a glance whether your Mac is paired, online, and protected. Alert history. Every event Rex has flagged, kept in one place so you can review what happened and when. Simple pairing. Scan a QR code once and your Mac and iPhone are linked. — How it works — WatchDog Key pairs with WatchDog on Mac via Bluetooth. Install WatchDog on your Mac, scan the QR code shown there, and you're connected. — Premium subscription — WatchDog Key offers an optional Premium subscription (monthly or yearly) that unlocks full protection: tamper alerts, remote arm/disarm, and automatic Bluetooth proximity locking. Subscriptions are purchased through Apple and renew automatically until cancelled. No account is required to subscribe. — Privacy first — We don't access your files, your screen, or the contents of your Mac. WatchDog Key only handles the signals needed to alert you and let you control Rex. Read our full privacy policy at watchdogapp.de. Built by LA Software UG in Germany.
