Awesome piece of kit best £20 I ever spent

Bait and switch

The updates are frequent and strangely always “Connection profiles database update. Bug fixes.” However since 2.2.28 a number of dashboard metrics which were previously available - such as DPF Regeneration - now flash behind “[Available in pro]”. Always happy to review a cheap money grab.

Feature heavy

I’ve never tried any other app, but I downloaded this one I paid for the premium and I get a dashboard no ads for seven bucks. It was cheaper than the OBD scanner I bought and it connects to it very well. It refers all the data and it seems pretty responsive. Actually only complaint is that I wish I could create my own custom dashboard layouts because they give you like preset ones that you could use to create and maybe there’s a feature in there that I haven’t found yet but essentially I can only use their templates and there’s a lot of of them, but there’s like one configuration I’d want that isn’t in there so I’m not even gonna ding them for that cause it’s so minor that the rest of the future make it better

Impressive

Works great. Zero complaints. What impressed me is the ability to set up your own customized live data viewing page. There are dozens of metrics of your vehicles various systems being monitored and you can select which ones you’d like to view and what sort of view, like gauge, graph, percentage and several orher variations. You can resize them and move around to build your own set up. Even further is you can go into these selected gauges and graphs and totally customize them; from colours,values, min/max and more. It’s one heck of an app for its simplicity on the surface and the depth you can get out of it.

Very good app

I purchased 2 ELK Bluetooth devices for about $8 on Amazon, and have never had a more thorough OBD two scanner directly on my phone for less than $10.
