This apps promise to reduce data usage. So far, seems legit because even Facebook had acquired the company. Minor nitpick (Seriously? What app I don't have any minor nitpick with?): It has constant notification and symbol that I can't find way to turn off.

How it works:
To compress and save your data, Onavo Extend runs continuously in the background of your phone and directs all of your mobile data traffic through Onavo's servers and compression technology. Revolutionary universal data caching means you won’t have to use your data to load the same images every time you visit a website or use an app because they’ll already be available to you on your phone. And don’t worry about local storage, because you control the percent of your phone’s memory used for storage.
Onavo Extend also optimizes images when you share over 3 or 4G so even when you’re sending images, you’re in control of how much data you use. And the Onavo Extend widget helps you easily monitor how much data you’ve saved so you can really understand how the app is working for you.
Onavo Extend is only supported for specific devices.
Some ROMs and kernels are missing important networking support that Android 4.0+ APIs and Onavo Extend rely on. If you've received a message saying your version of Android is unsupported, or if the app always says "service paused", please contact us using the Feedback link in the menu so we can help. Trying a different ROM or kernel should also help.
