"I do not need anything else but I want to set the time fast ..." Timer Holic is aiming for a different goal than many of the timer apps out there. We focused on things that were quick and easy to set up, rather than rich features. No matter what time you set, it can take a few seconds. Other features - Customizable alert message - Use up to 10 timers at the same time - Set time by second - Stopwatch (set time to 1 second) "Leave the small timing to Timer Holic and you pay attention to more important things."
