Grimeton

Leave your Mac at home. Your iPhone or iPad becomes its screen, keyboard, trackpad, speaker, microphone and camera, from anywhere, with almost no lag. Not a shrunken remote desktop: a real display, built for the device in your hand. A REAL MAC SCREEN Your Mac creates a display sized for your iPhone or iPad, at native resolution and up to 120 Hz, and streams it in hardware HEVC. Sharp text, Mac gestures, no pinching around a tiny desktop. On a good connection it feels local. YOUR MAC, ONE TAP AWAY A slim bar above the screen holds your Mac's desktops, all its apps with search, and the menus of the app in front, as native iPhone menus with their shortcuts. TALK TO YOUR MAC The iPhone's microphone becomes the Mac's. Dictate to your AI coding assistant on the Mac from the couch, the train or a café, and watch it work on a screen that fits in your pocket. Vibe coding, away from the desk. TAKE THE CALL When a Mac app needs a camera or a mic, Grimeton uses the iPhone's, with echo cancellation. Join a video call from the Mac at home, wherever you are. SOUND, ON YOUR IPHONE Music, videos and notifications from the Mac play on the iPhone's speakers or your AirPods. MADE FOR IPHONE DUO Fold it halfway and stand it up: your Mac's screen on top, a full keyboard below. A mini Mac. Hold it unfolded upright for desk mode, with the Mac screen filling the top and the Mac keyboard and trackpad open below. Held upright on a folded Duo or any iPhone, your Mac's screen sits above the keyboard and trackpad. MADE FOR IPAD A big Mac screen in a slim slab. Portrait desk mode with the keyboard and trackpad below, or landscape for the whole display. KEYBOARD AND TRACKPAD Pair any Bluetooth keyboard and trackpad. Shortcuts, scrolling with momentum and gestures follow your Mac's own trackpad settings. With AssistiveTouch, you get the Mac's pointer too. TOUCH THAT MAKES SENSE Tap to click, hold for right-click, drag to select with real handles. Taps land on the nearest control, not the exact pixel. The keyboard pops up when you tap a text field. Three-finger swipes switch Spaces and open Mission Control. FROM ANYWHERE, END TO END Runs over your own Tailscale network (free), encrypted end to end by Tailscale. Your screen never goes through a server, because there is no server. HOW IT WORKS 1. Install Grimeton on your Mac, free, from grimeton.app. It lives in the menu bar and walks you through the permissions. 2. Install Tailscale (free) on the Mac and on the iPhone or iPad, signed in to the same account. 3. Open Grimeton on your iPhone or iPad. Your Macs are already there, synced through iCloud. Tap one. Connected. A Mac on another Apple ID? First turn on “Allow a code” in its menu (under “iPhone on another Apple ID?”), then add it with its address and the six-digit code shown there. REQUIREMENTS • A Mac with macOS 14 or later running the free Grimeton app for Mac. A Mac mini at home is perfect. • An iPhone or iPad with iOS 17 or later. • Tailscale on both. • Optional: a Bluetooth keyboard and trackpad. PRICING Grimeton is free, with no trial and no limit. If you like it, you can leave a donation from the home screen, any time. A donation changes nothing in the app. No subscription. The Mac app is free. Named after the Grimeton radio station, the last working long-wave transmitter of its kind.
