I have an app on my phone called Dash Command. It connects over Bluetooth to a dongle I have plugged into the odb port on my truck. It gives a lot of information to the user using the information provided by the trucks computer. The mpg it calculates is pretty close to hand calculations, that's more accurate than the numbers on the dash using the same info. You want info on how the engine is running? It can help with that. You want 0-60 or 1/4 Mike times? It can do that. It's a fun tool to have.

I work for one Trucking Company that uses the GPS instead of Odometer mileage to see how many miles they have to pay me for.
I get paid by the actual miles that i escort the truck load.
Mileage begins when we leave the point of origin & ends when the drivers signs off my invoice at the final destination.

Sometimes their GPS & my Rams odometer are the same, other times we are 3 miles off on longer trips, like on a trip of 200 miles plus.
I know what causes the difference, the GPS is right on if we never changed lanes
If we pass any vehicle & have to switch lanes doing it, the GPS does not see the extra feet it takes to do that lane changing

I'm sure that trucking company is aware of that and it's just trying to save some money.

It is one of my more frequent companies, sometimes using me once or twice a week, other times just once a month.
So losing $1.50 a mile here & there does not really hurt me while doing a 200 mile trip

The main point is that the GPS APP is just a little bit off from the Odometer
BUT, the Odometer is off if the vehicle has changed tire diameters

The app mentioned in the original post doesn't use GPS, but gets all it's info from the trucks computer.

I'm so hoping you had someone else driving, or taking the photos/screenshots in the one showing a speed of 52 mph.

Can the Dashcommand app access trans temp, oil pressure or other proprietary codes? I have a different app but have yet to really put it to use in the truck. It worked in my old Monte SS.

I imagine its a screenshot pulled from a data log. Doesn't look like a pic someone took

Yeah, that's why I said screenshot as an option.
I have a similar app which bluetooths (it can be a verb, right?) to a dongle and I can instruct my phone to take screenshots of the real time monitoring functions that look just like that except the graphics are different.
I've done it while Mrs 9 was driving at various speeds, so while it's possible that those pics were produced without requiring attention be drawn away from the road, there's no reason to assume it.

It doesn't, but it would make it even better if it did.

There has been a lot of these apps around for years, some better GUI than others. I've had a GoPoint on my iPad for 10 years or so that does something similar. I can take it from car to car and it can keep track of a number of things for you. Its really an ODB port scanner with some presentation software. Some, like GoPoint, will do nice graphs for you, others just display the raw data.

In my experience, once the novelty wears off, it doesn't get used much other for troubleshooting like a ODB scanner would.
