## What is HamGrid?

HamGrid shows your Maidenhead locator on a map: six characters for where you are, big enough to read at a glance.

A grid that follows your zoom
HamGrid draws the Maidenhead grid over the map and switches levels as you zoom: fields for a continent, squares for a country, subsquares for a town.

Move the map, read the locator
Drag the map and a crosshair appears. The locator now shows the point under the crosshair. It's a quick way to check the square of a summit you want to operate from, or of the station you're talking to.

Search by locator or place
Enter a full locator and the map jumps straight there. Enter just the start, like JO5, and all matching squares light up at once. You can also search for a town, a street or an airfield.

Made for the air
• The zero has a slash through it, so you can't mix up JO and J0
• Tap the locator to copy it for your log
• A UTC clock right next to the locator
• The accuracy of your fix in meters, so you know how much to trust the locator
• A dark design that is easy on the eyes at night

Widgets
Small and medium widgets show your locator, the UTC time and a map of where you are.

Privacy
No account, no analytics, no tracking. HamGrid collects no data. Maps and place search come from Apple Maps.

Made by mucnoc in Germany.


## Version history (last 4 releases)

### 1.2.1 — 2026-10-10

Fixes for the widget and the grid.

### 1.2 — 2026-10-08

Fixes and a widget that's easier on your battery:
• The UTC clock now changes exactly on the second and always uses 24-hour time
• The grid now continues across the date line
• The location button now reliably resets the zoom
• The widget uses less battery and keeps your last position if a location fix fails
• Search no longer brings back old suggestions

### 1.1 — 2026-09-24

HamGrid now shows how good your fix is: the accuracy of your position, in meters, sits right next to the locator. At ±5 m the locator is solid. At ±2000 m you know to wait a moment.

### 1.0 — 2026-09-21

No release notes.
