Detect Metal

Three essential tools in one app. Detect hidden metal, find true North, and check if any surface is perfectly level — all offline.

Detect Metal puts three precision sensor tools in your pocket.

METAL DETECTOR Using your iPhone's built-in magnetometer, Detect Metal senses changes in the surrounding magnetic field. Get closer to a hidden nail, pipe, or metal object and watch the signal grow — with visual feedback and haptic pulses that intensify as you approach. Calibrate once, then scan freely.

COMPASS A clean, classic compass with a full rotating rose, cardinal directions, tick-mark dial, and a real-time degree readout. The red needle always points North. Works entirely offline — no GPS or internet needed.

SPIRIT LEVEL A precision bubble level using your iPhone's gyroscope. Place your phone on any surface to instantly see roll and pitch angles. The bubble glows green when perfectly level. Great for hanging pictures, leveling furniture, or checking construction work.
