My best tool

Glad I upgraded from my bulky notebook. This App allows me to quickly decide what I want to adjust. The forms section now allows me access to my notes anywhere. Best $12 I’ve ever spent.

Good app for beginners bit pricy for what’s there though

Good app for beginners who don’t know much about setting up cars. The app would be better if you could select multiple conditions you are experiencing at the same time and recommend adjustments based off that. Currently you can only select one conduction such as “loose in”. Also, other adjustments for dirt oval, or other types of racing would be a nice addition to justify the 12$ price tag. Overall the app is decent just needs some improvements to be great. The great thing about this app though is the 12$ price tag is only a onetime fee, whereas other setup help such as the VRS is a monthly fee.

Developer Response ,

if experiencing multiple conditions.. adjust for the condition that occurs first (that will have bearing on the other conditions)... ex: if you are loose in,mid and off - adjust for loose in first... then mid.. then off..
