The opening poster was obviously using the fuelly web app (last updated in 2014) not aCar. It's not a reasonable comparison to compare an app that no longer updated (fuelly web app) to the iOS app (updated in March, 2018).
It would interesting for someone who has used both aCar (latest version) and the iOS Fuelly app to list the differences for those of us who have never used an iPhone. Android only users don't know what we are missing (if we are).
I have been using aCar since it was first released. The only thing that I like about fuelly.com's involvement with aCar is the ability to sync across multiple devices.
