This is an in-development app to let some apps use mobile data always regardless of being connected to a WiFi network — to go over firewalls more conveniently.
This app is intended for devices which don't have a "Mobile data only apps" setting like Samsung.
Uses Flutter for UI rendering and Android's VPN service for the split-tunneling (using the word loosely here) functionality.
Although this app doesn't need root to run, you can't run this app simultaneously with another VPN app.
