Customer Reviews

Very helpful and informative app

I drive a Jaguar which always seems to have some or another indicator light coming on. This app, used with a $20 Bluetooth connected OBD2 transmitter has been so helpful in figuring out what is going on with my car on a day to day basis. It is widely customizable, connects flawlessly as soon as I open the app, and talks to my Jag it their own car language. No more $75 trips to the Jag dealer to see why an indicator light has come on. No surprises at the emissions check station. I recently lost battery power and had to jump start the car. All the indicator lights and messages come on, and it would have required yet another trip to the dealer to clear the engine light if it weren't for my handy dandy OBD fusion app. And I can watch my battery voltage on the dashboard. I do wish I could print out or save the screens or the snapshot details, so I just take screenshots to capture the information (takes 3 or 4 snaps to get all the info though).
Highy recommend the app if you are an iPhone user looking for a clear, easy, reliable OBD app.

Amazing app, great UI, great customizability

I originally used a free app to work with my OBDII wifi reader and was disappointed. I decided to buy this app and will say it is well worth $10. The UI is beautiful and the customizability of what stars you would like to display is incredible. The amount of detail in how the dash readings will look graphically is well beyond my expectations for this app. The app connects to my OBDII reader noticeably faster that the free app I was using before (OBD car doctor). The diagnostic tool is very nice as well and shows all engine codes. Highly recommend this app.

Irritating issue

Love the app and wish to give it more stars but here's the issue I have.
The app boasts that you can create dashboards and fully customize gauges. And I can...But only for the first 5 seconds the app is open.
When I start the app I can press and hold a gauge to change it. If I wait for more than about 5 seconds and then try and press and hold, nothing happens. I have to close the app and reopen and that gives me another 5 seconds to try and edit a gauge. So creating a gauge is a vicious cycle of
-Opening the app
-Pressing and holding a gauge immediately
-Making changes
-View new gauge
-Close app and reopen to edit more
If that could be fixed, easy 5 stars for the app
