Overall, very much worth the $!! I paid for this app, plus the enhanced diagnostic capabilities for my '21Mazda CX30. Ive tried many other OBD2 apps, even paid for the pro version of a few others, but in comparison to OBD Fusion, none have come close to providing the level of diagnostic capabilities as FUSION. This app has given me insight to inner workings of my vehicle that I didnt think was possible. Has already paid for itself 10 fold in the 2 months ive used it! Highly recommend!

Great app but unless I'm missing something there is no option for gauges in Android Auto. That was my only reason for purchasing this app and it turns out it's the same output in Android Auto as the free app without paying. The output is delayed as well so much so that the RPM is back to idle before the increase even registers. I'm using a VEEPEAK adapter too, not one of those cheap ones so that's not the issue. I'm pretty disappointed but hopeful the devs will add gauges. Edited

Unfortunately, Android Auto does not support creating dashboard or custom screens, so OBD Fusion has to work within the framework supported by Android Auto. Please reach out to us if you have any questions.

Update: I have once again found a fix. I turned off mobile data. I have it connecting 3 out of 3 times. Update: I am once again unable to connect to my wifi OBD2 device. I am still able to connect with different software (Car Scanner), so I don't think it's entirely a hardware issue. Ok, so following the instructions imbedded in a different app (OBD Mary), I found that by disabling battery optimization I could get it to work every time. You may want to include this information in your app. Edited

App works very well, though there are a few quirks. 80% of the time connection is super quick. The other 20% I have to retry 3-8 times. I would love to see the ability to show minimum and maximum read values in addition to current value. Also the ability to have a gauge tile change color based on current value would be fantastic. Current version app, toyota module, kiwi 3 Bluetooth obd adapter

Works well when it connects to a paired adapter. Problem is getting it to connect. Elm 237 Not sure but may be related to having internet access. Once I drive away from the house it often works when a cell connection is made. July 6, 2022 still fails to connect most times. Used the same adapter with others and connects easily but like this interface much better, just unusable Edited
