Sometimes it takes a while, I have had to delete and reinstall, turn the phone off and back on, reset and all sorts of things to get it to work at times when I first got it. It will not show KR and any of the normal functions like engine temp or timing. I have KR on one page and everything else on another. When I switch between pages it has to change so it takes about 30-60 seconds to reconnect. I use the phone for work and it's the only app on the phone. I like the app but I've had issues like that all along. It hasn't been a deal breaker, after all where else can you scan for codes, read live data and clear codes for less than $30?
