Turn your phone into a magnetic field scanner. Find the nail, the stud, the pipe behind the drywall — then ask AI what you're actually looking at. Lodestone reads your phone's built-in magnetometer and turns raw magnetic data into something you can act on. No extra hardware. No account. Works offline. WHAT IT FINDS - Nails and screws — locate the stud without guessing - Pipes, conduit and rebar behind walls, floors and concrete - Steel and iron objects at short range - Magnetic field anomalies and EMF hot spots - Magnetic north, with a built-in compass mode AI IDENTIFY — WHAT NOTHING ELSE DOES Every other detector app hands you a number and leaves you to guess. Lodestone sends the signal profile — peak strength, shape, duration — to an AI that tells you what it's likely reading, in plain language. "Sharp, narrow spike at 34 µT, consistent with a drywall nail. Sweep 16 inches left to confirm stud spacing." Add a photo and it reads that too. If a pattern looks like electrical conduit, it flags it before you put a drill through it. FIVE SCAN MODES Metal — general ferrous detection Stud & Nail — tuned tight for framing Pipe & Rebar — slower, for larger buried steel EMF — field anomalies and electrical noise Compass — heading from the same sensor BUILT FOR ACTUAL USE - Calibrates to your environment in 3 seconds - Audio tone, haptic pulse and visual gauge — use it without looking at the screen - Live 60-second signal graph so you can see where the peak was - Save finds with a note, photo and location - Daylight and red-only Night themes for sunlight and crawlspaces - Adjustable sensitivity and response HONEST ABOUT WHAT IT CAN'T DO Most apps in this category promise buried treasure. We won't. Your phone has a magnetometer, not a search coil. That means Lodestone detects iron, steel and magnets at close range — typically a few centimetres, further for large objects. It cannot reliably detect aluminium, copper, gold or silver, because those metals aren't magnetic. It is not a substitute for a professional cable locator, and it is not a safety device. Always confirm with a proper tool and check for utilities before you drill, cut or dig. If you want a treasure detector, buy a real one. If you want to find the stud, the nail, or the pipe in front of you — this is the sharpest tool on your phone.

Verdict
The clearest difference is in-app purchases: SphinxMD at none against Lodestone's 1. SphinxMD also leads on iOS requirement (13.0 vs 15.1). On price, ads and device support there is nothing between them.
