OSMTracker for Android is a free GPS tracking app developed by Laboratorio Experimental. It allows users to track their journeys, mark waypoints with tags, voice record, and take photos. The app is inspired by OSMTracker for Windows Mobile and is designed to cater to the needs of those who want to track their journeys with precision.

One of the most impressive features of OSMTracker for Android is the ability to export GPS traces in GPX format for later use with OpenStreetMap tools like JOSM, or uploaded directly to OpenStreetMap. Moreover, the app provides users with the option to display tracks over an OpenStreetMap background or with no background if they do not have a data plan.

The app requires certain permissions such as fine location to access GPS, record audio to record an audio tag, internet and network state to display map background and upload to OpenStreetMap, WiFi state to get coarse location, and write to SD card for GPX export. Overall, OSMTracker for Android is a reliable and efficient GPS tracking app that is worth trying out.
