Fuel!

Fuel! is an entirely automated app which guides you hands-free (without touching the iPhone) to the nearest gas station.

You just need to open Fuel! by activating Siri, the iPhone's voice recognition module (saying 'Hey Siri') then once activated you need to say 'Open Fuel! App'
Once opened, the app will direct you to the nearest gas station (may require confirmation from the passenger in Maps).
It will be possible to choose a different one from the list of nearest stations (by the passenger).

Here are all the functions:
. 14 native languages available (French, English, Norwegian, Danish, Spanish, Italian, German, Simplified Chinese, Russian, Swedish, Finnish, Portuguese, Japanese, Korean)
. Possible to choose a different gas station from the nearest stations (all manual actions to be done by the passenger)
. Activation/deactivation of automatic guiding
. Choice of units of measurement (metric or USA)
. Choice of maximum distance to find a gas station.
. Choice of guiding system (Apple or Google Maps if installed)
