Simple and to the point for emergencies

While this is not a 5 star app, if you're in a bind, and need help fast, having to scroll through menus and settings will stress you out, and that's where simplicity such as this is a big help.

I would say this is your best bet in an emergency, or if you just need to see your location quickly and easily, without having to reach for glasses. If, like me, you use higher diopter readers.

It's just the essentials... UTM coordinates, compass bearing and send. With a quick option to switch to Google for communicating with Nav challenged recipients.

If I need to communicate my whereabouts in a hurry, this will be my go to. It’s great for check-ins in Search and Rescue.

Now if someone would only offer this in a GPS watch, without the entire contents of the kitchen in unwanted "features", I would be in happy.

Update: Since the latest update, the app shows the all 6 coordinate digits at the same, now smaller, font size, Garmin GPS readout style. Whether you like this or not depends on individual preferences and application. Personally the old mapping convention (first 2 digits small, 4 large) worked better for me. I found it very useful for navigating to a waypoint with ease, watching the coordinates click up or down on the move without needing reading glasses.

Works, may require some setting-up

Initially, the UTM grids were off. I had to play with the datum settings for North America (selected NAD27). One I made the change and verified on my map, it worked perfectly. Used it to plot a small land nav training course and it was spot on. Great app when you don’t have access to a commercial unit.

Bottom line, make sure you verify the grid accuracy before using.

A gem of an app for UTM

I use UTM for off-trail backpacking and this app does exactly what I need and nothing more. I don’t want extra features because I’m using my phone very sparingly in The backcountry, and extra features equal extra battery use. 5 Star app. KEEP IT SIMPLE
