OpenVPN on Android without root
FEAT VPN is an Android app that brings OpenVPN to Android versions 2.1 through 3.2. In contrast to existing apps, FEAT VPN does not require you to root your Android phone or tablet and thus void its warranty. FEAT VPN works on unmodified off-the-shelf devices.
FEAT VPN comes in two versions. The free version, FEAT VPN Lite, is intended for people who connect to their OpenVPN server only occasionally and its use is limited to one hour per day. The commercial version does not have this time limit.
FEAT VPN is a Feats and Heroes project.
