Android app for calculating Roll Out and Final Drvie Ratios

Just wanted to let a few folks know about a new android app I just placed on the Android Market. It is named "Gears!". It is a simple rollout and final drive calculator.

It is version 1.3.1. It is a free app right now, so try it out and let me know what you think. You can post here for any questions or problems you might have.

I hope it is self-explanatory, but if not, here is a quick start...

When app first opens, you need to enter your cars Internal Drive Ratio. For pan cars/direct drive axles, you would enter 1.0. For all other cars enter the correct value, like 1.83 for a Losi JRX-S Type R touring car...

Next pick your tire type, foam or rubber. This determines if you are gonna calculate Roll Out or Final Drive Ratio. For Foam it will use tire diameter to calculate a Roll Out value. For Rubber, it will calculate Final Drive Ratio.

Next, you must enter values for all but 1 of the remaining fields. Then hit the calculate button. If you left a field blank, then that field will be calculated. If you have values in all the fields, then the Final Drive Ratio or Roll Out will be recalculated based upon the other values.

That is it. Nothing to fancy, but useful (at least to me). I am interested in fixing any errors you might find, and adding other features in the future, so feel free to post anything here (be nice ).
