O-Clock

O-Clock lets you have your own orienteering start clock!

O-Clock is a starting clock that indicates the starting time with five beeps.

With O-Clock you can easily add a title or a personal message.

O-Clock has six optional intervals of start time: every 10 sec, 15 sec, 20 sec, 30 sec, 60 sec or 120 sec.

New! We added the option to set a pre-start time. For example, you can use it as a two-minutes-to-start clock.

New! Stop watch mode: you can start the clock from zero instead of the current time. It is also possible to add a count down to zero.
