HyperMiler.co.uk MPG Calculator

A very basic app with adverts running along the top – but as it’s free, we can overlook this. Our biggest annoyance was that the app can only be used to work out one figure – it can’t be used to track consumption over time. And while HyperMiler allows you to post your MPG to Twitter, we can’t imagine anyone who would use this in reality. Gas Manager is the better free app.
