VPN-Private browsing of the internet
The main reason people use it to hide their IP address so that no one can track or trace them. If you are the one who wants full privacy while browsing then there is nothing better than this app. You can get them for free and there are some which required payment for downloading. Go for those which are trusted and secure to use. Also on the other hand it will be very helpful if you are using a public WIFI because your data can be stolen in no time.
