 This is an alternative Android Application for [WireGuard](https://www.wireguard.com/) with added features. Built using the [wireguard-android](https://github.com/WireGuard/wireguard-android) library and [Jetpack Compose](https://developer.android.com/jetpack/compose), this application was inspired by the official [WireGuard Android](https://github.com/WireGuard/wireguard-android) app.
