Knock Out App!!!


This is by far the best app I've purchased! The UI is smooth, logical, functional, and straight to the point. I was close to buying a real boxing timer then it hit me to search the apps store for one! I'm glad I saw this app, it saved me $150! And it does everything the professional timers do. Plus being able to hook it up to my big screen is awesome! Absolutely love this app! The audible warnings makes it so easy to stayed focused on my work out, no more clock watching. Love Love love it!!

Best APP ever


I never ever write reviews but something has to be said about this Boxing timer APP. This is the best $3 I have ever spent. A commercial timer is $150 plus. Now all I do is prop up my iPad or my iPhone and it's fight time with my boxing coach. I usually attach an external speaker so it's louder in the gym and once we start I don't have to fiddle with it the whole workout since rest times are included etc.. The APP only works in portrait, not landscape. But that's ok I guess. I love love love it!



There are many uses for this. I use this for boxing training. Music can be preloaded for a training mix or you can play your own in the background. I also received a text when using the app and it did not hinder its use, just kept on going. I was going to buy an actual training alarm but checked the app store first. Glad I did, exceeded my expectations past 5 stars. Nuff' Said!
