You don't have to count rep by rep. Here's an example of how it would work

You say "Bench Press." The app confirms with a beep.

You want to add the some weight to the bar and tell the app how much weight you are going to use. So you say "135 pounds". The app confirms with a beep.

You do your set, and you were able to squeeze out 9 reps. You say "9 reps." The app confirms with a beep.

Repeat.

It is 100% voice-controlled. I try to log my workout without taking my iPod out of my pocket the entire time I'm at the gym. At the end of the workout, I'll review all the sets because occasionally the voice recognition will get a few numbers wrong (ie, it might mistake 5 for 50).
