iPhone

Slide your iPhone over the wall to find the screws in the studs. Then mark them in AR and see every stud, so you know where to drill for a TV, shelf or cabinet. Magsense turns your iPhone's magnetometer into a stud finder. Slide the phone flat across the wall: when it passes over a screw or nail in a stud, it buzzes, beeps and shows the peak. Free to use, with a one-time Pro upgrade. THE SCANNER (FREE) • Finds the screws and nails that hold drywall to the studs • Haptics and an optional tone that rise as you get closer • Live signal graph, so you can see the peak • Shows where the sensor sits on your iPhone model • Low, normal and high sensitivity • Mark the spot with a pencil before you move on • Also finds other iron and steel in the wall: steel pipes, steel conduit and metal studs PRO: ONE PURCHASE, NO SUBSCRIPTION • AR wall map: pin one or two pencil marks with the camera and see every stud on the wall • Stud prediction: a 16" or 24" (400 or 600 mm) on-center grid calculated from your screws, or measured from two studs; any custom spacing works too • Hang planner: place a TV, shelf or cabinet and see which screws land on studs • Level line: a true horizontal line across the wall, with its height above the floor • Blocking: mark screws in the horizontal pieces between studs, so they aren't counted as studs • Ceilings and floors: map the joists the same way (turn it on in Settings) • Save your walls, take a photo with the overlay and share the plan GOOD TO KNOW • Magsense detects iron and steel, not wood. It finds studs through the screws and nails in them, so it works best on drywall over wood or metal studs. • Remove magnetic cases, wallets and MagSafe accessories while scanning. • Magsense can't see copper or plastic pipes, or ordinary electrical cables. No signal doesn't mean nothing is there: always check before you drill.

New: ceilings and floors. Turn them on in Settings → Advanced, then choose Ceiling or Floor in the ⋯ menu of the AR Map. Pin a pencil mark and Magsense draws every joist, just like the studs in a wall. On a plain white ceiling, a few pieces of masking tape help the camera.
