GPS Fuel Log+

應用程序，旨在遏制燃料欺詐

This is the paid version of the (free) GPS Fuel Log application which added several features and more importantly allowed back-up and restore operation from/to local resources and on Google drive.

The application is a fuel log mobile app with extra requirements:

- with each fill-up the user collects GPS information and takes pictures of the odometer and receipt

- only last fill-up operation can be modified but only for price information or to retake pictures of the odometer and receipt (the GPS info is not changeable)

- the app allows to operate fuel logs on multiple vehicles

- the user can view, browse previous fill-ups in detail (see pictures or the location of the fill-up)

As with any fuel log, reports, charts and statistics are provided.

The extra features which are not present in many competing products is to email, store locally or on Google drive the content of fuel logs. In consequence there are two ways to back-up and restore: from local storage or from Google drive.
