Psiphon Pro is a free and open source tool developed to help people around the World to bypass Internet censorship. This network always changes servers and it provides encryption in order to keep your traffic safe and hard to read. The application offers an option to Tunnel the entire device, but it only works if you're on Android 4.0+ and rooted.
Inside the user interface you can see the status of your connection and launch the built-in browser and start browsing the World Wide Web. This browser lets you configure your home page, add bookmarks and other functions that other web browsers are able to perform. Psiphon Pro does not require any registration and you just have to download and launch the app.
Another important feature of this tool is the ability to add applications to be excluded from the VPN tunnel. If you tunnel your whole device and your Dropbox stop working for example, you can add this app to be excluded. Inside the main window you can access the status, statistics and logs tabs. You can see the duration of your session, how much data was sent, received and compressed through Psiphon.
The application also puts at your disposal a Stop button if you want to close the session and use your Internet normally.
