Paywall

Some things I noticed is if you’re using a iPhone or android phone, you can do different things which they should tell you. With the android phone you can do more things. Another thing is the scanner is $40 but the subscription is $50. I might as well pay for another scanner and get another year for free. They should let you pay by the day, week or, year for the subscription. You only have one option pay $50 for a year. It says it can read my o2 sensors on my Honda but it only reads one. The scanner is good if you have nothing else but id say save up a little more money and get something you don’t have to pay to use.
