CoordTransform is an Android tool for conversion between Geodetic systems (latitude & longitude as provided by GPS) and Universal Transverse Mercator (UTM) system. It is a free app for Android that allows you to convert coordinates between the two most common systems in the world.

It is useful for people that want to create a map of some area on the ground or sea and want to be able to read the coordinates from the map. It is also useful for people that are going to do a hiking, biking, or any other outdoor sport and need to know the coordinates of where they are.

It is useful for people that are going to do a search and rescue or GIS where conversion between different formats is needed.
