This trial has all the functionality of the paid version except it only runs for 5 minutes and then automatically closes. Please try this version before purchasing the retail version to make sure your phone doesn’t have any issues with the program. **Note: Slight improvement to paid version over trial reference the AMRAP and Interval2 timers won’t start unless values are entered into the time variables.Ever lose track of how many rounds you’ve done during your AMRAP? I do all the time. Tired of trying to make chalk lines on the ground or putting beans in a cup? I was. I put together a timer that has a large button that you can easily press in between your rounds to keep count of your rounds. After that, I decided to add a separate Tabata counter/timer to keep track of your work/rest intervals as well as reps per round, user-adjustable interval timer, rest-specific interval timer, 20-lap timer, "Death By" timer, weight calculator and a general stopwatch with four timers on the same page. With links to view the Hero and Lady WODs online. This is a comprehensive set of timers for use during your Crossfit workouts. The timers can also be used for stuff besides Crossfit, just use your workout imagination! **Please note that while the timers are persistent and will continue to count if the screen is off or you switch to another program, the "back" button on your phone WILL CLOSE the timers app. To go back to the "Home" screen, always use the "Home" button at the bottom of each page. Check out a preview on YouTube that shows all of the timers’ functions: http://www.youtube.com/watch?v=AHpUj1R3J9E
