Aimed primarily at cutting fuel use, the VELOcar app lets users set personal goals for gas reduction. It then monitors how they drive and gives tips for what they can do to meet and exceed their goals. Along with giving tips, VELOcar shows how much gas one could save by following different strategies. As an added push, and making fuel conservation more of a competitive game, VELOcar shows a driver's performance compared to their family, friends and even other drivers of similar cars. In addition to showing a driver's fuel economy score, VELOcar gives a score based on carbon emissions and also displays a user’s score trend for the previous month. VELOcar is free and works through the mojio device. It currently allows comparison among drivers of Toyota Hybrids, Nissan Sentras, Chrysler Concordes, Dodge Caravans and Hummers.
