What is Real MPG?

Real MPG is a real world fuel economy register with more than 100,000 MPG submissions from our readers. Unlike official fuel consumption figures, Real MPG uses real life comparative data to show car owners and buyers how much on-the-road fuel a vehicle uses – so you can make accurate predictions as to how much fuel you will use and be better prepared as to how much that will cost.

I have downloaded to my iPhone 5s but it will not register my ID entries. I have tried a couple of email addresses and a couple of variants on my name. Each time I go back to the login it tells me that I am not a registered user.

What am I missing please ?

I have downloaded this to my iphone 5s but it will not register my details even though I have tried a couple of email addresses and variants of my name.

What am I doing wrong please?

Why not a mass market android app as well as a niche iPhone one?

My overall mpg on my Zafira 1.6 diesel is currently 57 mpg, with quite a high proportion of short distance driving , almost 50/50 long short. I can get well over 60 mpg on long runs. My overall mpg on my 1.7 litre Zafira was better at 59 mpg average , on a higher mileage engine.
