## Description

Digital Angle Finder: 3D Meter is a mobile tool for precise angle measurement. It uses your device's accelerometer and gyroscope to determine the angle between two surfaces, and in protractor mode it can measure the angle between lines on a plane.

With an estimated accuracy of 1 degree, you can capture and save measurements by taking a photo with the measured angle recorded for easy reference, all wrapped in a clean, user-friendly design.

## Review summary

Reviewers praise the app when it functions: it's easy to use, can provide accurate measurements, is ad-free, and helps with ROM tracking without a physical goniometer. However, multiple users report reliability problems, with the app failing to measure or producing inconsistent results (e.g., readings like 172-179 degrees). Several also cite poor or unclear instructions. Overall sentiment is that the app is helpful in ideal conditions but unreliable in practice, with a need for better guidance and stability.

### Pros

- Easy to use / simple interface
- Accurate readings when it works
- Ad-free / no tracking or upsells
- Useful for ROM measurement and progress tracking

### Cons

- Unreliable / sometimes doesn’t work
- Inaccurate readings or wrong angle measurements
- Poor or unclear instructions / help
