## Description

Compass is a lightweight, stable, and precise compass app built for outdoor adventures and everyday navigation. It provides real-time north, azimuth, and DMS coordinates, supports magnetic declination and auto-calibration with gyroscope and accelerometer, and offers a Stable Mode that filters noise for a smooth needle—perfect for hiking, camping, sailing, photography, and stargazing.

The app includes GPS and map integration to mark directions and locations, a night mode and battery saver, and offline core functionality so the compass works without internet. Privacy-focused permissions request location only when needed to improve GPS accuracy. Professional calibration and an intuitive interface help you find accurate direction quickly and reliably.

## Review summary

User reviews show strong praise for the compass's ease of use and general reliability when it works. However, many reports indicate the app sometimes fails to run or crashes on certain devices, and there are frequent concerns about accuracy variability. Some users want elevation data and units (feet) shown, and a few cite device compatibility issues. Overall, the app is liked by many, but stability and accuracy across devices are common pain points.

### Pros

- Easy to use and quick to get a direction without excessive waving.
- Works well and performs reliably when it functions.
- Broadly positive reception; many users praise the app (excellent/outstanding, 'I love this app').
- Simple, straightforward compass that does what it's supposed to do.

### Cons

- Not working or crashing for multiple users (issues with installation and runtime failures).
- Inconsistent accuracy across users/devices (reports of ~30° offset vs notes of very accurate).
- Incompatible with some mobile devices.
- Elevation/altitude information is missing and users want unit options (metric/feet).
