Grid Ref UTM is a free travel and navigation app available on Android. Developed by Mike Irving, this app allows users to pinpoint their current map reference location anywhere in the world using the Universal Transverse Mercator (UTM) geographic coordinate system.

With Grid Ref UTM, users can obtain UTM Grid Ref, Hemisphere, and WGS84 Latitude and Longitude values for their location. The app also displays the accuracy of readings as indicated by the user's device.

One of the key features of Grid Ref UTM is the ability to share your location via text, email, tweet, or by copying it to the clipboard. However, it's important to note that sharing options and services may vary depending on the device setup.

This app is designed to operate internationally and even includes a graphical guide to the United States (USA) UTM Zones. It is particularly well-suited for walkers, hikers, and outdoor sports enthusiasts. However, it is always recommended to carry a map and physical compass when engaging in outdoor pursuits.

Grid Ref UTM is compatible with handsets that feature GPS hardware, although users may need to grant the app permission to use this information.

Please note that Grid Ref UTM is ad-supported, but users have the option to remove all ads through an in-app purchase.
