Needs work

I'm only giving it 3 stars because I tricked it to work. Need a way to set differential gear ratio. I tried calculating speed of new xmaxx. Found several calculators that work great online and figured I'd try the app. The only way I managed to get the app to produce close to accurate speeds was to set cell voltage to 3.75 and cells on 2. I'm appalled that I paid for an app that isn't actually accurate when it's marketed as a calculator.

Great Trackside Tool! 👍🏼🔧

It's accurate, easy, and intuitive. Make trackside gearing decisions with confidence. No problems at all from download to everyday use, it works like a charm. For those of us old-school guys, the email and export features make keeping a hard-copy record easy to do.
