Looking for this app

[prodigiez]

Is there an app which has the ability to block upload and allow download vice and versa ?

There are firewall apps for Android and they need root access.

You just could turn of wifi and mobile data?

its impossible to totally block upload then be able to download any or vice versa.
if you know the 3 way tcp handshake then you know its true.
