5. Onavo Extend (Free)
Onavo Extend helps you save mobile data (images and documents you download from your phone) so you can do more of what you love on your mobile device without spending more on your bill. Bonus: the app also tells you how much data you are using and where you are using it.

6. EBay (Free)
It’s no secret that Ebay is a treasure trove of deals. You just have to be savvy enough to navigate the site, which can sometimes be a pain. But the updated and upgraded app is faster than the website and allows you to easily save past searches.
