Análisis de la app Net Blocker: App Firewall para 10 de septiembre

Net Blocker is a per-app firewall that lets you decide which apps can go online — and which can't. Block internet access for any app over Wi-Fi, mobile data, or both, with a single tap. No root. No remote servers. Everything runs locally on your phone. Stop background apps from wasting your data, silence chatty apps, cut off tracking and ads at the source, and take back control of your connection. ► HOW IT WORKS Net Blocker uses a local VPN service to build a private, on-device firewall. When you block an app, its network traffic is simply dropped — nothing is sent anywhere, no packets are inspected, and no data ever leaves your device. There is no root required and no account to create. ► KEY FEATURES • Per-app internet blocking — turn any app's connection on or off instantly • No root needed — works on any Android phone or tablet • 100% local & private — no servers, no logging, no data collection, no ads • Home dashboard — see protection status and every blocked app at a glance • One master switch — enable or pause the firewall in a single tap • Auto-start on boot — protection resumes automatically after a restart • App Lock — secure the app with fingerprint, face, or device PIN • Block-attempt alerts — get notified when a blocked app tries to connect • Light & dark themes — clean Material You design ► PRO FEATURES • Unlimited app blocking — go beyond the free 3-app limit • Block Wi-Fi only or mobile data only — fine-grained control per network • Quick Settings tile — toggle the firewall straight from your notification shade • Auto-block new apps — newly installed apps are blocked automatically • Block scheduler — turn protection on or off automatically on a daily schedule • Profiles — save different block setups and switch between them in one tap, with a home-screen widget • App groups — block or unblock a whole group of apps at once ► WHY NET BLOCKER ✔ Save mobile data by stopping background usage ✔ Improve privacy by cutting off apps that phone home ✔ Reduce distractions by taking selected apps offline ✔ Extend battery life by limiting background sync ✔ No root, no ads, no tracking — just a firewall that works ► PERMISSIONS Net Blocker is a no-root firewall built on Android's VpnService, used to run a local, on-device firewall that blocks selected apps from the internet. This may show a "VPN" key icon in your status bar, but Net Blocker is NOT a traditional VPN — it does not route, tunnel, or send your traffic to any remote server. Your traffic never leaves the phone; all filtering happens on your device, and blocked apps simply can't connect. Download Net Blocker and control exactly which apps can connect.
