I am thinking of app (IOS, and Android) where you do the following.
* Post Links (Youtube, Twitter, and Instegram) and convert them into many format in order to download them.
* Work as converter for Photo and Video.
* Work as compressor for Photo and Video.
* Ads removal (distinguish) ads in websites and block them so you can see videos freely.
* Podcast (Photo, and Vedeo) into TVs and Chromecast.
