Purple Services – On-demand gas delivery right to your car

Launched an app/service that lets you order gas for your car and it will be delivered right away. We drive to your location and fill up your car. I developed the app as an HTML5 app. Would like to know what you think. Criticism positive/negative is very welcome. Thanks!
