I use the Android app from Wireguard: https://play.google.com/store/apps/details?id=com.wireguard.... It's pretty basic, but it lets me scan the generated qr codes, and it has an icon in the drawer which makes it easy to access.

Rethink DNS on fdroid is great. Way better than the official wireguard android app: https://github.com/celzero/rethink-app
