## Description

Stud Finder: AI Metal Detector uses your phone’s built-in magnetometer to detect ferrous metals behind walls. It measures magnetic field changes in microteslas (µT) and displays real-time readings. Features include automatic and manual calibration, a sensitivity slider, and a Hold button to freeze values. It works offline with a simple, intuitive interface to locate studs, nails, screws, pipes, and other magnetic materials.

How it works and practical tips: Calibrate at startup to establish a baseline, then interpret readings above baseline to identify metal objects. Common ranges include nails (+5 to +20 µT), studs (+80 to +150 µT), and strong sources (150–300+ µT). For best results, remove cases, keep electronics away during calibration, and use the back/top of the device where the sensor sits. Use cases include drywall stud locating, hidden hardware detection, and scanning around devices.

## Review summary

The consensus is overwhelmingly negative. Users report the app fails to reliably detect wall studs, gives inconsistent readings, or no readings at all. The paid upgrade is repeatedly criticized as costly and ineffective, with trial prompts interrupting use. Instructions are unclear and the app quality is described as poor. Many reviewers request refunds or dispute charges. A few tests mention temporary results with non-wall objects (such as knives), but this does not translate into a reliable wall-stud detector.

### Cons

- Does not reliably locate studs on walls; reviews show no readings or inconsistent results.
- Paid upgrades are intrusive; high costs (2.99 or 5.99) with upgrades not improving performance.
- Poor usability and unclear instructions; user interface and directions are confusing.
- Widespread dissatisfaction about charges and refunds; users request money back and question the ethics.
