aCar is a one-stop shop of an app when it comes to keeping track of car-related details. The app can record servicing, parking fees, and, yes, fuel. The last thing on this list attracted the eye of Fuelly, a company whose website helps users calculate their vehicle's fuel economy. It purchased aCar back in May, and now the Android app is receiving its first update since the acquisition.
Version 4.8 doesn't shake things up too much, but it does take some steps towards integration.
