    If you cannot see: your speed, engine rpm, temperature coolant temperature and battery voltage on your instrumental cluster and want to see the on your iPhone’s screen then use this app. It can also read O2 sensor and some other parameters. It supposedly scans for trouble codes. Not sure if it can scan fir enhanced diagnostics. Overall it is a basic app for its price. It could have cost $2-3 for the limited capability it has. Pros: -See your instrumental cluster on your iPhone screen and save a log of them. - scans for basic trouble codes - shows times engine start, travel time and fuel economy Cons: - scan is very basic. Display configuration is useless. Ant even change the units( e.g. time engine start in seconds! Not even minutes! -cannot change or code any feature -there is no free version or trial to try before purchasing -some pids are not working. Example remaining fuel I do not recommend it. ,
  • Great App. Save me thousands.

    Purchased with the Veepeak Code Reader. I had rodents get into my car. It was throwing around 16-19 codes. Yea...just crazy. Had to keep running up to a local garage to get a reading each time I repaired a wire. This WILL clear your codes. YOU DO NOT NEED TO GO TO THE DEALER!!!!! That's a lie. Within a week I'm down to zero codes.
  • Very neat

    Works well.
  • Great app

    By Masdeath
    Requires some skill to use and could use a few more preset gauges and dashboard styles. You also have to import several PIDs if you want more access to sensor data. Over all great app. Lag is nonexistent using an lelink ble adapter and iPhone 5s displaying 4 or less gauges. You get more lag the more gauges you use at a time, could be the software, adapter or phone, not sure which. Would like to see a Pontiac specific addition, to access some more in depth features on the pcm.

    The app connects well with my cheapie Amazon OBD2 unit. Best is their customer service.
  • Works well, a suggestion

    By CobraA1
    My biggest suggestion would be to not tie the ranges to the templates - they tend to be specific to the gauge. Would also like to see more fonts for the digital display.

  • Logs MPH and GPS from Automatic Pro perfectly

    By SirDap
    I was looking for a way to log OBD-accurate speedometer and geolocation so I can correlate them with decibel measurements I'm taking with an external SPL meter. Since I already use an Automatic Pro, I wanted to find an app that would stream from it so I wouldn't lose the crash alert feature. After trying a few apps (Harry's Lap Timer was overkill for non-lap drives) I found this app absolutely wonderful to use!! The pairing was seamless, and the CSV data is clean and intuitive. Dashboard of gauges is very clean and definitely a plus. Would recommend to anyone using an Automatic Pro!
  • Second impressions...

    By Awdterror
    So I've edited my review an added 3 stars, and here is why: customer support and their ability to respond to reviews to address concerns, big plus here, it shows they are actively aware and engaged in making the app better. Second while you have to go through menus to activate them, there are additional PIDs for ford and gm. If those weren't available, this would of been a deal breaker for me. Third, the app is updated regularly and looks modern with digital readout gauges. Overall as long as it proves to be as accurate as dash command I'll make the switch. One thing I would like to see in the future is min max values on the digital read out gauges in addition to current values.
