Adverttu is a free iPhone app that allows you to earn money while you drive. By becoming a "mobile ambassador" for leading brand advertisers, you can earn up to £150 a month. The app wraps your vehicle with cool vinyl advertising and protects it at the same time.

Adverttu manages the entire process, from selecting advertisers to scheduling your car wrap appointment. Best of all, it's completely free to use.

All you have to do is track your mileage, and you'll get paid every month for each mile driven. If you're looking for an easy way to make some extra cash, download the Adverttu app today and join their family of ambassadors!
