Fronto is a cash generating app by swiping your screen lock. When you unlock it, Fronto features deals and offers by sponsors that when clicked on, earn you points.
You must sign-up via email or with Facebook before using Fronto. Points can be exchanged for cash and the amount of points earned depends on how interactive you are from reading an article to downloading an app.
Fronto is an easy way to make small amounts of cash but you'd have to use it a hell of a lot to earn serious money.
