Just a bit of info I recently came across. There's an app in the Android store, not sure if there's an iPhone version or not. It's called "Break Speed" and it's powered by Predator. It's $5 and it's pretty darn handy. I'm not a shill by any means, just like the app and wanted to share. You select the table size, where you're breaking from and hit the timer. You have 1 minute to break. It recognizes the sound of when the cue ball is hit, then when it hits the rack then does the math.
I haven't calibrated it against a chronograph but it seems like it's in the ball park, we spent about an hour with 4-5 of us going back and forth using it at the pool hall a few weeks ago. Turned into a little "competition" after a while.
Here's a screen shot to give you a bit of an idea what I'm talking about.
Enjoy it if you choose to.
