I found an app recently, it's UC Browser

It can save the videos from the web in cache, like youtube. So you can save the video in your phone, and watch it anywhere,even without net connecting!

What's more, it have the feature Wifi-Sharing, we can transfer the files between phones and computers under the same Wifi network!! When i download some beautiful picture from the mobile web,i can transfer the pic to computer to share to my friends.

I think UC Browser is really really great!!! you can search "UC Browser" in appstore to download it
