Bad App
Will not stay up long enough to make a proper diagnosis using my iPhone 6 Plus.
Crashes
App had promising functions however on the second minute of using it crashed and now its in constant loop of crash, not recommended unless they update it. And thats on iphone 5/ios8 which apparently its optimized for.
New update
Since new update was released, system doesn't start on iPhone 5s!
Very Good
Fast data. Nice layout.
Connection
Was a very good app until the latest updates now I can't even connect to my bluetooth elm 327,which I've connected to in the past.
