Ratings and Reviews
Amazing App for Scan Tool
I purchased the Veepeak OBDCheck BLE OBD2 Bluetooth Scanner and this app plus its add-on for my vehicle family. This app recommended the Veepeak scanner. Its site recommended this app. It sounded like the perfect combination for an app-based scan tool, so I got them both. I couldn't be more pleased!
The scan tool, I think, is very good. It gathers the complete OBDII required data and, it appears, any extensions the vendor adds.
This app is infinitely configurable. It appears to be able to collect the full OBDII set and any and all vendor extensions. However, they may require the purchase of add-ons within the app.
There are two screens of "instruments" that come with the app. You can add more screens and instruments and fully customize them to display data the way you want to see it until you go blind. Looking into the settings, I can't imagine there's anything missed.
I'll also add another plug for this scanner/software pair. I believe the Veepeak is the only one for iOS that doesn't connect using Wi-Fi. It connects via Bluetooth LE. Also, you don't pair it. OBDFusion connects with it directly. This makes setup very easy and, more important, it leaves your Wi-Fi, cellular data and Bluetooth untouched and available! Very nice.
Good program, needs some work
This works well with my OBD2 dongle. The information seems accurate and helped me when buying a used car by showing me the error codes, which I showed the dealer. He then gave us a new battery based on the report with no change in the price of the car.
There are a few annoyance. It does not connect with the Bluetooth with out some finagling. Once the phone is turned off, it loses the connection. The data does not seem to be saved. Once I use it on another car, the data for the first car is lost (or I can’t find it). It “forgets” vehicles so I have to to re-enter the information when I change cars. It would be nice to be able to download the information to a desktop for storage.
Overall works well for diagnostic information but it would be nice to store each car’s information and be able to reference it later.
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.
Developer Response ,
OBD Fusion doesn't have enhanced diagnostics for GM, but it does have some GM specific PIDs that you can import including knock. Open Settings > User-Defined PIDs and press Menu > Import built-in PIDs.
