START TIMERS INSTANTLY With Instant Timer, you can start timers quicker than with other apps. HOW IT WORKS Other timer apps usually require you to first set a duration before the timer can start. With Instant Timer, it's the other way around: First, you start a new timer. Then, while this timer is already running, you set its duration. This is why timers can be started so quickly with Instant Timer. LESS STRESS With Instant Timer, you first start a timer and then set the duration afterward. That way you can take the stress out of the moment and set the duration when it suits you best. GREAT FOR COOKING Imagine you are cooking. The water boils, but you also must hurry to finish chopping the vegetables. You quickly put the ingredients into the water - but for how long again? Take the heat out of the moment: Start a timer for the water now, finish chopping the vegetables, and then you have all the time in the world to dig out the recipe and set the water timer's duration accordingly.
