In a nutshell: Double your monthly data usage by compressing data through Onavo and start getting more bang for your buck.

Available on: iPhone/iPod Touch/iPad/Android

Price: It’s FREE.

Why do I need it?
Using Onavo means you can end up spending much less on your monthly phone bill if you - like us - find yourself repeatedly exceeding your smartphone dataplan. Or it simply means you can surf more, without worry of hitting your limit.

How does it work
Onavo compresses the data you use on your phone when you do things like surf the web, download emails, access maps and even when you log in to other apps such as Facebook and Twitter. It can reportedly save you up to 80% of your data.

Minimise spending abroad
One potentially very useful thing about Ovano is that it works in 90 countries worldwide, so expensive roaming rates can be greatly minimised.

Monitor what is costing you
You can also use Onavo to monitor what apps are eating up the majority of your data, allowing you to catch out specific apps that end up costing you more when your phone bill arrives. Just send those ones to the bin and start saving instantly.

It does have limits
There are some things Onavo can't compress - content streaming apps (like iPlayer or Youtube), Sykpe, video calling, downloading music, games, or vids and uploading content.
