NeonLock

Lock your Mac the instant you step away. Tap once, or let NeonLock sense the distance over Bluetooth and lock it for you — automatically.

NeonLock turns your iPhone into an instant lock button for your Mac. Tap once and your Mac locks over Bluetooth — or set a distance and let it lock itself the moment you walk away. No passwords to fumble, no menus to dig through, and nothing in the cloud.

HOW IT WORKS NeonLock comes in two parts: this iPhone app, and NeonLockMac — a small, free companion that runs in your Mac's menu bar and does the actual locking. Install the Mac helper once (a quick, free download; link inside the app), pair over Bluetooth, and you're set. No account, no sign-in.

TWO WAYS TO LOCK • Tap to Lock — Press the button and your Mac locks instantly, whether it's across the room or in your bag. • Walk Away to Lock — Choose a distance; when your iPhone moves out of range, NeonLock locks your Mac for you. If the Bluetooth link drops while you're away, it still locks. (Auto-lock runs while NeonLock is open.)

BUILT FOR REAL LIFE • Multiple Macs — Pair as many as you like, switch the active one, or lock them all at once. • Fast access — A Control Center and Lock Screen control puts a lock one tap away. • Always ready — NeonLock reconnects to your Macs on its own, so it's there when you need it. • Protect the app — Optional Face ID, with a PIN fallback, keeps NeonLock itself private.

PRIVATE BY DESIGN NeonLock talks to your Mac directly over Bluetooth. Your data never leaves your devices and never touches a server — no accounts, no analytics, no tracking.

PERFECT FOR • Coffee shops, coworking spaces, and open offices where you step away often • Anyone who wants their Mac locked the second they leave it • People tired of reaching for the keyboard just to secure the screen

Setup takes under a minute: install the free NeonLockMac app, pair it with your iPhone, choose your locking mode, and you're protected.

Download NeonLock and never leave your Mac unlocked again.

REQUIREMENTS • iPhone on iOS 16 or later • A Mac on macOS 26 (Tahoe) or later running the free NeonLockMac app • Bluetooth enabled on both devices
