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.

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.

New for version 3.0: An interactive grid square map lets you find the grid square for any location!

Very useful app

I find this app to be invaluable when operating in the field. The user interface is very “clean” and easy to read when glancing at the phone.

The new grid square feature and map is interesting but without a text search feature for addresses it’s of minimal value. I’d ask that the GPS coordinates field be restored. I frequently used the GPS coordinates to enter my location data on other apps or during web searches.

Useful for portable ops

I like this app for portable operations away from the shack. The redesign of the UI is very nice!

I noticed one issue. The 12H local time on my phone shows 24H time. My phone is set to 24H. Not a big deal, but thought you might like to know it’s off.

Yes, the Maidenhead doe not work and sunset time does not display either. As a clock it works and has a nice very readable large display. de N6GYR
