Pool Clock is designed for interval-based training during swimming exercise. This app simply reproduces the traditional analog swimming pace clock found on the pool deck. By placing your device or a TV monitor connected to the device at the poolside, you can start swimming workouts wherever you are. Be careful to keep your electronic device waterproof when use it poolside. *** Interval *** With the interval function, you can easily track the interval on the pace clock. Once you set the Interval Time, Iteration (the number of interval repetitions), and Preparation time (time before the first start), a small triangle appears on the outside of the dial of the clock to indicate the next start time. *** Digital Clock *** The digital clock can be displayed or hidden using the ON/OFF button in the menu. The digital clock displays the current time of the device. You can choose between 12-hour or 24-hour display. *** Sound *** You can turn on/off the countdown beep sound in the menu. *** Notice *** This app prevents the screen from turning off while it is open.
