Upgrade your experience. Try CoordTransform, the fantastic Tools app from Santiago Martinez, from the comfort of your laptop, PC, or Mac, only on BlueStacks.
CoordTransform is one of those small, no-nonsense tools that does exactly what it says. It converts between latitude and longitude and UTM without extra fluff, which is great when someone needs a quick answer out in the field or at a desk. It supports a bunch of reference ellipsoids, with WGS84 as the default, but it does not transform between different datums. So it expects the user to know the right datum going in. Latitude and longitude can be typed in three ways, decimal degrees, degrees with decimal minutes, or full degrees minutes seconds, and the app keeps everything tidy and readable.
The map screen is the part that stands out. Drop a marker, drag it around, and it updates both geographic and UTM values instantly. It pulls from GPS or lets the user punch numbers in by hand. Copying to the clipboard is just a long press, and sharing a coordinate to another app is quick. On a PC through BlueStacks, the mouse makes fine adjustments on the map easier, and a keyboard helps avoid typos with long strings like DMS or UTM zones. It suits hikers, orienteering folks, bushwalking, mountain biking, kayaking, surveying, SAR teams, even casual GIS tasks, basically any moment where a map grid and a GPS do not speak the same format. It feels practical, a bit utilitarian, and fast to learn, which is honestly what a coordinate converter should be.
Switch to BlueStacks and make the most of your apps on your PC or Mac.
