Calm, invisible security
Walk away, lock away.
A lightweight macOS menubar app and iOS companion that automatically secures your Mac when you leave your desk, and arms when you return. Built natively in Swift.
Why we built it
We wanted a security tool that didn't demand attention. No constant notifications, no draining your battery, and no complex setup. Just a simple, reliable lock.
Invisible and calm
Mac Locker lives quietly in your menubar. It doesn't send you alerts or demand interaction. It simply watches for your phone's Bluetooth signal and acts when needed.
Battery efficient
Engineered with ultra-low power Bluetooth LE. Your iPhone acts as a passive beacon, meaning zero background battery drain while it protects your computer.
Total control
Need your Mac to stay awake during a presentation? Just hit Pause. Want to lock it from across the room? Open the iOS app and tap the manual lock button.
