Gamification in apps like this can incentivize consumers to increase usage of your app. More frequent users ultimately increases your revenue from advertising and other potential sources. My idea is that you should incorporate a point/coin system that rewards users for driving miles using Waze. These points can then be used to buy avatars and icons in place of the boring arrow that represents the driver. The more points you save up, the cooler avatars you can buy. Potentially, the points can be used for gift cards and other rewards that you may come up with. In the end, this idea is a unique differentiator in the GPS navigation market that can truly set Waze apart from competitors. Please take this under consideration. Thank you!
