WireGuard

It's okay, but there are some major "user experience" category annoyances. Like most of you, I'm using this to connect to a Wireguard instance running at home to access my home network resources on the go. The problem with this app is that it will enable the VPN tunnel on your phone, even if it doesn't make contact with the remote server. This essentially black-holes all your phone's traffic, cutting it off from all network access. The VPN should NOT be enabled if it can't connect to the servr

Updated from 3 to 5 stars now that split tunneling has been added. No more disabling VPN for banking apps, and I can route heavy apps outside the tunnel—e.g., transfer files to my NAS over VPN while streaming video normally. Reliability feels improved. It can also be controlled by other apps, so I use Tasker to auto‑enable VPN when away from home. Tip: set DDNS as the endpoint to avoid re‑downloading configs when the WAN IP changes.

absolutely best for the VPN for the self host. It's easier to setup and connect even for newbie. I hope that Android can have an option to choose for exception when connected to a WiFi I set for exception to make disconnected from the VPN, I saw it in iOS version but it can't be seen in Android. another one is make scanning QR code to add tunnel more easier, because I used iPhone to scanned it and it easy to scan but I scanned by two Android it difficult to scanned.
