GPS coordinate converter (v1.1) manual

Hello. I'm Android Boy, the chief developer of Smart Tools co,.

6 years ago, I developed a GPS coordinate API for Smart Compass. It was hard to understand and code UTM / MGRS. I wanted something that could reuse the API. And some of my unit converter users were requesting a separate GPS coordinate conversion app. That's why I released this app.

※ Introduction video

※ Main tabs
The app is based on WGS84 system that is most widely used. It shows 6 types (DD.dddddd˚, DD˚', DD˚ MM'", UTM, MGRS and Address). It also includes Google Map for easy use.

1. WGS84 : Coordinate conversion and new coordinate input. First select a coordinate type. To copy, double-tap the coordinate.
2. Map : The location on the map of the entered coordinate. Long-click to make a selection.
3. History : List where the entered coordinates are stored.

※ Location permission
The app requires location permission to determine your location. I realize it is a personal and sensitive permission. If you need to know where you are, allow it.

※ Menu & Settings
- Sound effect : on/off
- Text size : small, medium, large and huge
- Map types : default, satellite and terrain
- Map lock : disable swiping the map left or right
- Button position : specify the position of the RED floating button.

Q. How to remove the ads?
A. Payment is required. Go menu > ad-free

Q. How to copy coordinates to the clipboard?
A. Double-tap on the coordinates.

Q. I need another coordinate system.
A. It is difficult to support local coordinates. I'd like you to provide me with information about the new system/type. Please contact me at

 What's new
 - v1.1.13 : Android OS 14 support
 - v1.0.4 : Map types
 - v1.0 : GPS converter released (May, 2018)
