The new iPhone app is out and downloadable.
HOWEVER...... there are a few bugs that need to be worked out as the gear chart only allows you to chose from 3 pinions and 3 spur ratios. I think the scroll bar on each hasn't been "turned on" to allow the scrolling.
Some of the cars in the selections are spelled incorrect (no biggy) but the ratios on a few are incorrect.
Otherwise all of the features are really easy to use and will make keeping track of racing set ups very handy to not only record but keep track of and share.
