Preen Display turns an iPad on a stand into a live, glance-able display for widgets you ask for in a sentence. Tell your AI coding agent what you want — a TV remote, a revenue ticker, a security-camera feed — and the free Preen hub for Mac publishes it onto your iPhone. No code, no dashboard builder. Just a sentence. HOW IT WORKS 1. Run the free Preen hub on your Mac (preendisplay.com). 2. Ask your agent for a widget ("Make a power button that turns my Samsung TV on and off"). The hub's bundled MCP server and CLI do the rest. 3. The widget opens on your iPhone. Want a change? Ask your agent to publish an update. Widgets are plain HTML, CSS, and JavaScript — so you can also write and publish them yourself with the Preen command-line tool. IF YOU CAN SAY IT, YOU CAN GLANCE AT IT • A TV remote — on and off • What's playing right now: one big album art • A live security-camera feed • One-tap buttons for your busiest Slack channels • A focus stopwatch to keep your head down • Today's revenue, in numbers too big to ignore PRIVATE BY DESIGN No account required. By default your phone talks directly to your Mac over your own local network — your widgets and their data stay between your devices. TRY IT WITHOUT A MAC Tap "Preview a widget" on the first screen to see a live demo widget right away. PREEN PLUS (optional subscription) Preen Plus adds remote access: an end-to-end encrypted relay that keeps your display live when you and your Mac aren't on the same network.

Find the stud before you drill. Stud Finder turns your iPhone's built-in magnetometer into a magnetic stud finder. It picks up the steel nails and screws that hold drywall to the studs, and warns you about the pipes, rebar and conduit you don't want to hit. Lay your phone flat on the wall, let it calibrate, then slide it slowly. The gauge climbs as you get closer to metal, and the scanner lights up, beeps and buzzes when it finds something. THREE SCAN MODES Stud Mode: Tuned for the small, brief signal of a nail or screw. Follow the line of fasteners to find the stud. Metal Mode: Less sensitive, so only larger metal like pipes, plates and steel studs stands out. A line of nails won't set it off, so you can tell a fastener from a pipe. Deep Scan (Pro): The most sensitive mode, for fasteners set deeper in the wall that Stud Mode can pass right over. WALL VIEW (PRO) Found one stud? Point your camera at the wall and Wall View draws a line on it in AR, then marks where the next studs should be at your stud spacing: 16 or 24 inches, or 40 or 60 cm. Slide your phone onto a predicted line to check it, and tap to confirm. Predicted lines are estimates. Doubled studs around doors, windows and corners can break the pattern, so check each one with the scanner before you drill. FEATURES • Calibrates against your own wall, so readings fit the room • Live field strength in microtesla (µT) or milligauss (mG) • Low, normal and high sensitivity • Haptic and sound alerts: one beep for a possible stud, three for metal • Save scans and look back at them later • Keep the screen awake while you scan • A step-by-step guide that walks you through hanging a shelf, from the first stud to the last screw • Available in 13 languages FREE AND PRO Stud Mode, Metal Mode and calibration are free. The free plan includes 3 scans of up to a minute each. After that, watch a short ad for another scan, as often as you like. You can keep up to 5 saved scans. Stud Finder Pro adds: • Deep Scan • Wall View • Unlimited scans with no time limit and no ads • Unlimited saved scans If your plan starts with a free trial, we'll remind you two days before it ends. HOW IT WORKS, AND WHAT IT CAN'T DO We want you to know exactly what you're getting. Your phone's magnetometer senses magnetic fields, so it detects ferrous metal: steel nails, screws, pipes, rebar and conduit. Wood isn't magnetic, and no phone can detect it directly. Stud Finder finds studs the way a magnetic stud finder does, by finding the metal fasteners holding them in place. That's why the app reports what it finds by signal strength instead of claiming to identify materials. If a reading in Stud Mode is unusually strong, it tells you it's likely metal rather than a stud. Results depend on your device's magnetometer, the wall material and how deep the metal is. Detection is less reliable through thick plaster, tile, concrete or metal lath. Always check before you drill, and never rely on any app alone where there may be electrical wiring or plumbing.

Verdict
The clearest difference is rating: Preen Display at 5.0 against Stud Finder App's 4.4. Preen Display also leads on ads (none vs shown) and update cadence (weekly vs every 2 months). Stud Finder App's advantage is ratings volume (5 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
