Block Apps Internet Access

Decide which of your apps can reach the internet. NetMaster is an app firewall without root: one switch per app, separately for Wi-Fi and mobile data. Flip it, and that app is offline. Everything else stays connected. BLOCK APPS, NOT YOUR PHONE • One switch per app — block on Wi-Fi, on mobile data, or both • Covers preinstalled and system apps too, if you choose • Blocking is instant, and so is undoing it SCHEDULES • Off at bedtime, back by breakfast — set a window once, NetMaster applies it every night • Pick the apps each schedule blocks; the rest stay online • A warning before a window starts, so it never surprises you ESSENTIALS ONLY • One mode that blocks everything except the apps you mark as essential • For focus hours, travel data, or handing your phone to your kid SEE WHAT'S GOING ON • A count of every blocked connection attempt, per app, day by day • Data usage split by Wi-Fi and mobile, so you can see which apps use the most • Live traffic, as it happens PRIVATE BY DESIGN Android only lets an app filter traffic through a VPN connection, so NetMaster creates a local one on your device. There is no NetMaster server: traffic you allow goes straight to where it was already going, traffic you block is dropped on the device, and nothing is uploaded, shared, or sold. No account, no sign-up. No root required. Works on Android 7.0 and up. Available in 18 languages.
