# Stud Finder

An Android application that turns the phone's built-in magnetic sensor (magnetometer) into a stud detector. It operates by detecting the magnetic signature of steel screws and nails driven into wood studs behind drywall.

## Key Information
- **Strategic Positioning**: "The honest stud finder — built like a real tool, not a gimmick app."
- **Platform**: Android only (requires a device with a built-in magnetometer).
- **Core Technology**: Samples magnetic flux density at 50 Hz to detect ferrous anomalies (screws/nails).
- **Limitations**: 
  - Detects metal fasteners only; does not directly measure wood density.
  - Works on drywall over wood studs.
  - Does not work on plaster walls (due to wire lath) or metal-stud walls (the entire stud is magnetic).
  - Cannot guarantee detection of live electrical wires, plastic pipes, or hidden cameras.
- **Compatibility**: Requires a phone with a magnetometer sensor (approximately 14% of Android devices lack this sensor). Compatibility checks are run for free in-app before any subscription purchase.
