My first discovery of OBD is week ago and I know very little. But I notice a lack of sensors reading in pyobd compared to torque on wife's android. If i'm not mistaken, some data is calcuated from car profile if you insert (correct) data, like power, torque, fuel in tank....
But even if you dont insert data and the phone doesn't have any idea how much fuel you have, it display how many kilometers you have to empty and fuel consumption. Long story short... all data that you can see in car dashboard and more. Car is WV Golf 5.

Edit:
Today I compared sensor list and found that is missing:
average trip speed
distance to empty
fuel flow rate
liters per 100km
trip distance
trip time
