## Description

HamClock is a handy clock with features for amateur radio operators!

One screen shows your local time in 12H and 24H format along with UTC in large, easy to read text. If your location is available, your grid square, local sunrise and sunset are also displayed.

An interactive grid square map lets you find the grid square for any location, and displays the current gray line.

Flip to landscape mode for a larger UTC time display. Great for keeping track of things while operating.

On your watch, you can also quickly display your grid square and location.

HamClock is great for finding your grid square while traveling, or use it as a handy clock in your shack.

## Review summary

HamClock is praised for its clean UI, grid square feature, reliable UTC with DST handling, and a large, readable display—especially useful in portable/field ham ops. However, recurring issues include Maidenhead grid problems, removal of GPS coordinates, 12H/24H display inconsistencies, weak Apple Watch support, and a map feature many users see as unnecessary.

### Pros

- Clean, simple UI that is easy to read.
- Grid square locator feature is a standout for portable use.
- Accurate UTC time with reliable DST handling.
- Large, readable display ideal for field use.
- Portable and field-friendly design for on-the-go ham operations.

### Cons

- Maidenhead grid inaccuracies or it not working as expected (grid display issues).
- GPS coordinates display removed in newer versions; GPS field loss reduces usefulness.
- 12-hour/24-hour time display inconsistency; local 12H time may show as 24H.
- Weak Apple Watch support; grid square or location not shown on the watch, plus a non-informative app icon.
- Map feature added but viewed by many as unnecessary or intrusive.
