OpenVPN Connect is the «official» application developed by OpenVPN Inc. and is intended to be more user-friendly VPN users with little technical expertise. It is, therefore, less featured than openvpn for android which is designed for more advanced OpenVPN users.
Openvpn for Android, a free open-source client designed by Arne Schwarzbe, enables users to connect to any VPN service that supports the OpenVPN protocol. If your device isn’t compatible with the pre-configured VPN apps that are available in Google Play Store, this is a great alternative. The setup is fairly simple. You just need to import your VPN profile files (the configuration files have an extension of.ovpn) which you can find on the website of your provider or by calling their live chat support team.
When you’ve imported a profile, simply tap on one of the servers in the list in order to connect to the server. Once connected to the server, all Internet traffic is routed through a secure tunnel and directed to the http://openvpnandroid.com/nordvpn-vs-ipvanish-vs-expressvpn-vs-openvpn/ chosen server by the application. The Status tab allows you to check your connection’s details and status. The kill switch is on by default. It will block your internet connection when the VPN tunnel is cut off.
The application offers a per-app VPN as well as an always-on option that automatically creates the VPN connection whenever the app is opened and keeps it running even after your device has gone to sleep or switched networks. However, this feature requires Android 7.0 or higher and could draw more power from your battery than usual.
