Start a timer by knocking/tapping on your iPhone! Your iPhone can even be in your pocket!
The Nok timer is the essential interval timer for cooking in the kitchen, working out at home or the gym, studying at home, or other small tasks that require repetition. Nok allows you to customize up to 5 timers with individual names and times for the ultimate interval timing experience. No need to go through the lengthy process of unlocking your phone, finding your clock app, and resetting your timer — simply knock twice to set it again. You can even tap the alarm on or off through your pocket!
