Maidenhead Converter is a simple tool that translates between latitude and longitude coordinates and Maidenhead Grid Locator System coordinates.

- Track your current location in both latitude and longitude coordinates as well as Maidenhead Locator System coordinates at the same time
- Enter a latitude and longitude coordinate to see its Maidenhead Locator System equivalent, or vice versa
- View locations and a Maidenhead grid on a built-in map

What's New

Version 2.3.1

• Improved the layout of the coordinate panel in Split View on iPad

Ratings and Reviews

Nice tool


There's not a lot to say here, this just does what it's supposed to. You can use it to get your current grid square, with precision all the way out to eight characters, or it will convert from latitude and longitude to grid square and vice versa. An added bonus is that it will let you zoom all the way into a map and see the actual location. I tried this with my own a character grade square and sure and off the pain was right on top of my house. Nicely done!

Simple and easy


Great straight, forward app. Easy to use.

Problem Solved


I am an old timer who is new to six meters. This application is exactly what I have needed. No one takes the time to give out QTHs - just grid square. I use a beam and want to max out their signal with the rotor. That is best done by knowing where they are located due to fast fading. Problem solved! Clean & well thought out program because it shows you threir approx. QTH on a map. CQ six EM12 AF5U K
