    Says unable to connect to service can’t even log into my JB4 account
  • No CarPlay??? Seriously?

    I spend $600 on the JB4 and another $28 on this app and I have to keep my phone out to see the gauges. Insane. Despite that, app works great. CarPlay is a no brained addition.
  • Great app

    By Vcharmoy
    Love the app just wish it had CarPlay capability!
  • False advertising

    Does not work with the JB for USB. Doesn't say that it does not either. The day before Bluetooth was not compatible with my day before and there was no clarifications online about that either. Overall such a waste of time trying to get this to work.
  • Won’t go past “handshake “ on either of my devices. On second unit and no change

    At a loss
  • Keeping the app updated

    By Kaveh H
    The overall experience of the app is good however I’m surprised to why the developers do not release the capability for apple CarPlay
  • It works most of the time.

    I’ve been using this app for about 3 weeks now and have had to delete it and download it again twice because the text on the goes inverse for no reason and won’t switch back. Other than that it does what it’s suppose to do.
  • Great support

  • Limited gauges

    By jpiparo
    As JB4 uses odb2 and clear codes I would think I could get temperature gauges another OB2 readings for the price
