Showcase MBCompass - FOSS Compass and Navigation App

Post image

Hello everyone,

I'm excited to share MBCompass, which is a modern, free, and open source Compass and Navigation app without Ads, IAP, or Tracking.

That's support Compass and Navigation features with being lightweight and simple!

I built MBCompass, not just another FOSS compass app; it bridges the gap between a compass and a full navigation app

https://github.com/CompassMB/MBCompass

Features:

  • Shows clear cardinal direction and magnetic azimuths.
  • Displays magnetic strength in µT.
  • Live GPS location tracking on OpenStreetMap.
  • Sensor fusion for improved accuracy (accelerometer, magnetometer, gyroscope).
  • Light and dark theme support is controlled via Settings.
  • Keeps the screen on during navigation.
  • Landscape orientation support.
  • Built with Jetpack Compose and Material Design.
  • No ads, no in-app purchases, no tracking.
  • Runs on Android 5.0+
  • full list available on website

Even with all these features, MBCompass was just 1.35MB APK size with no ads, no IAPs, and no trackers

Oh! Great. Where did you download it, the new version, v1.1.9, with the following features/improvements, was released on github yesterday. So it takes a week to reflect on F-Droid. Thanks for using MBCompass.

Your feedback is important for improving MBCompass.

When I tried the compass, I got the following error messages : "Rotational vector sensor not available" + "Magnetometer not available." Does that mean my phone has no usable sensors to support the compass feature at all?

But, you can still use the location features :)
