Almost there – CMS Lap Timer Pro Review

Well for use at the track only it offers the best iPhone interface, but there is only a very limited way of viewing this on the computer. Maxq data is the only option for pc users and the company is no longer in business. Harry's laptimer uses circuit tools on the pc which is much more helpful as it can automatically assign beacons and allow you to change them for equal sectors max speeds or both min and Max allowing you to separate the corners or even break them down into corner entry and exit. Much more helpful IMHO to find the last few tenths around the track.
