yes, all the blinking lights and graphs are cool, but since i'm not a racing car engineer i don't know what 80% of this stuff are and how to see if something is wrong with the car and how and where to do something in the setup to react to what i see. i know it is my problem not knowing stuff and not an issue of the app, that do what is meant to do perfectly and merit five star for that, i actually give 5 star to tyre buddy and to camber extravaganza that very easily show what the car is doing and how the car change after tune the setup. this app is too obscure for me. Other apps as i said made obscure stuff like car geometry easy readable even to people who doesn't know anything about setups. this app don't do that and doesn't help me at all. Maybe you should add a document where you explain how to setup the car based from what you see in the graphs. this would help a lot and i will change to 5 stars.
