Turn your iPhone into an honest stud finder and metal detector. Sweep it across a wall and feel it react to hidden nails, screws, metal studs, steel pipes, and rebar — no cooldown timers, no pop-up traps, and nothing ever leaves your phone.
Download on the App StoreBuilt for DIY homeowners, renters, and hobbyists who want a quick, honest pocket check — without the tricks.
It finds magnetic metal — nails, screws, metal studs, steel pipes, rebar — not bare wood. A 30-second guide teaches you how to use that to locate any stud.
Other apps freeze the tool for 10–20 seconds until you pay. We never do. The full live detector — both modes — is free, with no countdown and no scan limits.
It reads your iPhone's built-in magnetometer — no camera, no account, no internet. Nothing about your scans ever leaves your phone.
Three steps from blank wall to marked spot.
Remove your case (especially metal or MagSafe), hold the phone flat, and set a baseline so the gauge reads true.
Glide the phone slowly across the surface. The radar gauge climbs and the µT readout rises as you approach buried metal.
Haptics and an optional audio tick peak right over the nail or screw. Use Peak-Hold to lock it, then save and label the scan.
A phone’s magnetometer senses magnetic (ferrous) metal only: nails, screws, metal studs, steel pipes, rebar, bolts, and brackets. It does not detect bare wood, copper wire, copper pipe, gold, silver, or aluminum. To find a wood stud, you find the nails or screws holding it in place — the app shows you exactly how. Always confirm with a probe before drilling, and never rely on it alone to avoid live wiring or pipes.
The full live detector is free, forever. Upgrade for power features — never to unlock the basics.
An honest pocket metal detector that runs entirely on your iPhone — no upload, no account, no cooldown.
