Great app and worth the money.
I have tried free apps for obd2 and this one is far superior. A $20 wireless reader device + 1 days Amazon shipping for $10 + $10 for this app = $40.
Way cheaper than even the low end obd2 readers from the auto parts store which go from $60 to $250.
This app works flawlessly and automatically connected to the device I bought off amazon.
If anyone gets a check engine light they should try this first so they can go to the mechanic knowledgable before they start recommending to replace part$ randomly
