Simple and Easy App to determine various-format coordinates
# User-friendly Design #
Your location is instantly displayed in the center as a grey-line intersection. You may locate yourself by simply inputting a value, searching by name of place/city/state/country, or importing locations from clipboard.

# Support of Various Coordinate Formats #
Not only the app specifies Longitude / Latitude, but also supports a number of coordinate formats and systems, i.e., Universal Transverse Mercator Coordinate System (UTM), Military Grid Reference System (MGRS), World Geographic Reference System (Georef), etc.

# Datum Conversion #
The app is able to transform coordinates within EPSG , ESRI, IAU2000 references from online database, and convert X & Y coordinates, geodetic datums and projected systems.

# Tracking and Navigation #
Pin your desired location on the map to start navigation. Real-time bearing/distance update and large coordinate readout for on-the-field usage are available.

# World Magnetic Model Calculator #
The app utilizes World Magnetic Model WMM 2015 and/or WMM 2015v2, and is able to compute geomagnetic-field values: i.e., magnetic declinations, intensity, magnetic grid variation, etc.

# Elevation / Altimeter #
Elevation/altitude data is accessible within landmass area.

# Import / Export - AirDrop supported #
- Export current coordinates list to standard .gpx file and/or custom-made .txt format.
- Import/Open previously-created .txt file to migrate or backup coordinates data between devices.
- Import/Open standard .gpx file sent from other applications or GPS devices.

# Distance measurement #
Distance is measured by pinpointing locations, or drawing lines to create your own route.

# Bearing Calculation #
Initial bearing and final bearing between coordinates points can be calculated.

# PROJ.4 Calculator #
Transform point coordinates from one coordinate system to another, including datum transformations using PROJ.4 cartographic projections library.

# Apple Watch Support #
Apple Watch support is available, allowing you to view the coordinates of your current location in various formats.

It would be much easier if

It would be incredibley easier if you could type in an address or city or even a street!!!

Suggestion for the app

Great watch app.

It’s Simple, open it up and see your location!


It would be a top notch app if in the settings you could set a preferred mode to see your location in.

For example, I would prefer to open the app up see my location in MGRS every time...

And I’m sure there is some aviators and sea captains that would prefer so see longitude/latitude every time...

Anyways I’m sure there are many users that agree, this app would be an easy 5 of 5 if there was a way to set a preference on location display mode.

Oh and if I could put that in one of my watch complications...

I would probably pay for that.

Address to mgrs

I’m a military medevac pilot and would love if I could put in an address or intersection and the the mgrs for it. Having that could better help save lives.
