  •  Once installed, SimpleTimer can be started directly from the clock face by taping on Seconds
  • If SimpleTimer is counting when put into background mode
    • Seconds will be green if it's in countdown timer mode
    • Seconds will be blue if it's in stopwatch mode
    • Seconds will be white if SimpleTimer has been paused/reset
Standalone mode
  • SimpleTimer can also be installed as a standalone App, in this case,
  • Tip: For Sense and Versa 3 watches, use the watch Settings to assign SimpleTimer
  •  to the watch long press short-cut for easy starting.
  • For All watches, SimpleTimer launch icon can also be moved to the first Apps screen on the watch.
