HamGrid – QTH Locator Map
Maidenhead grid square locator
Only for iPhone
Free
iPhone
Your Maidenhead locator at a glance. For any point on the map, HamGrid shows its locator, distance and bearing, along with UTC time and date.
HamGrid shows your position on a map and your Maidenhead locator in large type, along with the accuracy of your fix in meters.
The grid
HamGrid draws the Maidenhead grid over the map and adjusts it as you zoom: fields at continent scale, grid squares for a region, subsquares for a town. One tap turns it off.
Any point on the map
Drag the map and a crosshair appears. The display then shows the locator and coordinates of the point under the crosshair, and its distance and bearing from your location. By default, HamGrid uses the straight-line distance from your exact position. In the About screen you can switch to the IARU contest rule, which measures from subsquare center to subsquare center, the way distance-based VHF contests are scored.
Search
Enter a full locator and the map goes straight there. Enter only the beginning, such as JO5, and all matching grid squares are highlighted. You can also paste coordinates or search for a town, a street or an airfield.
On the air
• The zero is slashed, so you never mistake O for 0
• Tap the locator or the coordinates to copy them for your log
• UTC time and date next to the locator
• A dark design that is easy on the eyes at night
• Know your grid square for SOTA, POTA and WWFF activations, roving and VHF contests
Widgets
The small and medium widgets show your locator, the UTC time and a map of your location. The medium widget also shows the UTC date.
Privacy
No account, no analytics, no tracking. HamGrid collects no data. Maps and place search are provided by Apple Maps.

New in this version:
• Distance and bearing from your location to the point under the crosshair. By default this is the straight-line distance. You can switch to the IARU contest rule in the About screen.
• Coordinates below the locator. Tap to copy them, or paste coordinates into the search to go to that point.
• The UTC date in the app and in the medium widget.
• After a search, the map now centers exactly on the result.
