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.
