Figured I chime back in....

I installed shot timer pro for $10. Got it to the range and it did what it said it would do.

I set it up for my 1911, seemed to work fine. I'm going to see if the same profile will work with my ARs or another caliber of handgun.

Bottom line, for 10 bucks it's not bad. It works.

BTW, I have a Motorola Razr- not sure if the newer OS and hardware makes a difference.
