Introduction

FireWall Blocks lets you cut an app off from the internet, on Wi-Fi, mobile data or both, without root. It has two ways of doing it, and you can use either or both at once.

Two modes

  • Shizuku mode (recommended by the developer): the firewall rules are applied through Shizuku, and the app doesn’t have to keep running in the background. After a reboot, start Shizuku first, then open FireWall Blocks once to re-apply your rules.
  • VPN mode: works immediately with no setup, by routing traffic through a local VPN on the phone. Nothing leaves the device through someone else’s server. The catch is that Android allows only one VPN at a time, so this mode can’t run alongside a real VPN app.

Features

  • Per-app rules for Wi-Fi and mobile data separately.
  • A network monitoring screen (VPN mode) that shows which apps are trying to connect, with block and allow buttons right in the live log.
  • Import and export of your rules as a JSON file.
  • Sorting and filters: user apps, system apps, apps with network permission, disabled apps, rules left over from uninstalled apps.
  • App search.

What stands out in the APK

  • Shizuku API confirmed in the code. No trackers.
  • Acts as a VPN (BIND_VPN_SERVICE) is the special capability that VPN mode uses. Android asks for your approval the first time you turn it on.
  • Notifications is the only permission that asks first. The rest are ordinary install-time permissions: network access, a foreground service, starting at boot and seeing installed apps so it can list them.

Installing it

  1. Install the APK.
  2. For Shizuku mode, install and start Shizuku first. For VPN mode, nothing else is needed.
  3. Tap Enable, pick a mode, then tap the Wi-Fi or data icon next to any app to block it.
