KO Clock is the easy to use round timer for Boxing, Mixed Martial Arts and any circuit based training where you train against the clock rather than counting reps. Not only for professionals, but for anyone who wants to improve their workout regimen. It features the ability to set the number and length of rounds, the length of intervals and rest periods, and a configurable delay before the first round if you need extra time to get ready. It saves your last session for immediate use when restarting. As you train with KO Clock you will find that perfect setting that will help you get the most out of your training workout while still allowing intricate fine tuning as you advance in your fitness goals. KO clock can also be paused with a simple touch of the screen, and has audio and visual alerts including an audible warning ten seconds before the end of each round. Each alert sound can be turned on or off separately from within the options menu and you can play your music while KO Clock is running.
