Some users desire NAD83 support or the ability to change the map datum, and a few note missing watch compatibility or copy/paste formatting options. Overall, the app is valued for clarity, speed, and a no-frudge coordinate-display experience.

Would be nice if included NAD83

This is a great app for search and rescue. Numbers are large and easy to read out in the field and I see it in UTM for SAR use but also in lat/long for helicopters.
