A free app for Android, by LEAP Encryption Access Project.

This application is a VPN (Virtual Private Network) client using OpenVPN.

Bitmask allows you to connect to any VPN server or proxy using your mobile or laptop, and it will automatically detect the server you want to connect to.

It supports multiple protocols, including OpenVPN, IPSec, IKEv2, and others.

You can choose between automatic configuration, where the server is configured for you, or enter your information and choose which protocol to use.

If you are on Wi-Fi, the connection will be faster and more stable.
