If you are sick of paying over the odds for your fuel, then WhatGas is an app you should certainly download. This app will use your smartphone or mobile data connected tablet's GPS chip to find the petrol stations closest to you with the cheapest fuel prices. Whether your vehicle takes diesel, petrol, or LPG, this app will help you save money. Data is created by users of the app, so if you have any updated prices, upload them to help the community of WhatGas users!
I have made this our number one recommended app as I've personally saved £27 a month by using it!
