Gas Cubby
This is a serious contender to stay on your phone. It logs your economy, servicing bills and things like tyre pressures, plus reminds you when maintenance is due. The app is easy to use, and there are graphs which take up the entire screen in landscape mode. We’d prefer it if there were fewer American references (liters, US gallons, etc), but this is still a great app to check your consumption, and is a quid cheaper than our Best Buy.
