Awesome App – CMS Lap Timer Pro Review

I bought this app to use for auto-x and hill-climbs. It works great! I've only been able to use it for auto-x so far but it is very accurate and give's you all of the information you could ever want about your run. It will tell your speed at any point on the course and G-forces. You have to buy an external GPS receiver to cover for the inadequacies of the phone, but that's a small price to pay to turn your iPhone into a $1000 data logger. It will also auto start/stop the video so you don't have to worry about missing your best run. Also the developer responds to feedback and emails quickly. You can tell he is very interested in making this the most thorough data logging app possible on the iPhone. I highly recommend this app.
