I heard about them awhile ago but never tried it as I was worried about a random company just coming out and having access to all of my data on the web + logins/passwords. I remember hearing though that since it reduces your data usage by 80% that you basically would get 1GB worth of data on Att's $15/mo 200mb plan

Now that they have been out for awhile and have almost 2000 ratings w/ a 4.5 star average has anyone used this app? Does it really help shrink your data usage? Does it slow down your data speeds?

Thanks for the info

Like Onavo, but data slow down...

I have used Onavo in the past with the iPhone 4 and did not notice any perceptible data slow downs. However, I recently started using it with my 4S and I do notice slowdowns. These are backed up with speed tests running through speedtest.net. My ping times go from 70-100ms to 160-190ms and the dl data drops 1-2mb/sec on average. Say from 4.5 mb/sec to 2mb/sec. I was just doing a web search on this when I tripped across this post. I am looking to see if others are experiencing this as well.

When I remove Onavo, data speeds go up and ping time lowers... Re add and data speed drops and pings go up... This is consistent in the 7-8 trials I have done...

The compression Onavo states DOES happen though and on a limited plan, this could be huge savings.

You can't shrink your data usage by 80% without sacrificing something... Does it tell you how it shrinks your data usage?
