UltraGauge (OBD 2)

★★★★★ A friend had this in his vehicle, so I looked into it. Based on the reviews I hesitated.... I went ahead and purchased, and I'm glad I did not listen to those reviews. First, this company provides a lot of documentation, in the form of a thick manual, online support such as FAQ, and knowledge base, and you can actually reach a live person via online support. But I found all the info I needed in the manual. It was trivial to pair and connect. The gauges are graphically customizable. The app itself has run without issues and I am very happy with it. One thing that was key...was that I used my old S5 phone which was just collecting dust in a drawer. I mounted the S5 in the vehicle and the resulting solution is ideal. I did not want to use my current S6, as I did not want to deal with mounting and unmounting every time I got into the vehicle. My one issue was that you can download what they call "manufacturer gauges". But I did not even know about these, and I only stumbled across it in the manual. These downloadable gauges are apparently unique to your vehicle, but provide some of the best gauges, like transmission temp.

★★★★★ Great diagnostic tool I gave it 4 stars only because I feel like it is lacking one simple thing. When you rotate a gauge, I wish the gauge title didn't rotate as well. For instance the horsepower gauge in the sample picture above. Horsepower should stay horizontal while the gauge numbers and needle rotate to the desired degree. Also, selecting background colors is glitchy. I can only get 2 of my 4 color picks to appear. Lastly, fuel economy gauge is WAY off for Land Rover Discovery.

★★★★★ The app provides a nice interface to the new version of Ultragauge which, over the years, saved me many trips to the garage. The graphs are a very useful extension indeed which allows overlaying the readout for both the O2 sensors and the fuel consumption. It would be great to be able to scale separately the fonts for the digital output and the labels.

★★☆☆☆ This is a horrible company. Nothing is supported on their webpage. I would advise not buying this product.

★★☆☆☆ Abandoned product. Sorry that I purchased the adapter that lacks Android 12, and probably 13, support. 4 years with no app updates is too long for any software product.

★★☆☆☆ UpDate: Average MPG now reads O.K. but now Fuel Level Calc % is not showing properly. Original post: Average MPG always reads 100mpg which throws off other readings such as Gallons Used, Trip Cost.

★★☆☆☆ Close to sending the gauge back and asking for a refund The app performs very poorly. When I add gauges the changes I make to them will either not appear or the gauge will disappear. I'm totally unable to change anything without every other gauge on the screen being removed
