About this app

Network Monitor shows exactly how much data your phone and your apps use - and how fast your connection is - all on your device. No ads, no tracking, no analytics, no account.

LIVE INTERNET SPEED
- Real-time upload and download speed in your status bar and an optional notification.
- Toggle the indicator instantly from a Quick Settings tile.
- Several clean, minimal indicator styles.

DATA USAGE AT A GLANCE
- Today's and this month's data, split between Wi-Fi and mobile.
- Set a monthly data plan (limit + billing-cycle start day) and get a calm alert before you run out.
- Optional daily budget to stay on pace.

PER-APP BREAKDOWN
- See which apps use the most data, with a Wi-Fi vs mobile split for each.
- Open any app for details and a recent-days chart.
- Search and filter to find heavy users fast.

USAGE HISTORY
- Browse day by day, by month, or by billing cycle.
- Tap any day to see that day's top apps.

DATA SAVER + APP BLOCKING (opt-in)
- Turn on Data Saver to stop chosen apps from using mobile data, or block apps entirely.
- This optional feature uses Android's VpnService to run a local, on-device firewall (a local VPN). It affects only the apps you choose and forwards nothing off your device. There is no remote server, no VPN tunnel to any server, and no traffic logging. The firewall is off by default and only runs when you turn it on.

MADE FOR MODERN ANDROID
- Material You 3 design that follows your light/dark theme and dynamic color.
- Fast, lightweight, and battery-conscious.

PRIVATE BY DESIGN
- Your usage data never leaves your device.
- No ads. No trackers. No analytics. No advertising ID. No account.
- The app reads only your device's own data counters. The optional firewall is local only.

FREE, WITH AN OPTIONAL ONE-TIME PRO
All core monitoring is free, with no ads ever. A single one-time Pro purchase (no subscription) adds:
- Custom firewall profiles
- Per-app schedules
- Custom per-app data caps
- Premium indicator styles and a true-black AMOLED theme
- CSV export of your usage
- A home-screen widget (today's data, live speed, start/stop)
- Automatic Data Saver while roaming

AVAILABLE IN MANY LANGUAGES
Network Monitor is translated into dozens of languages.

WHY THESE PERMISSIONS
- Notifications: the live speed indicator.
- Usage access (optional): the per-app breakdown and history.
- Internet and VPN (VpnService): used only so the optional on-device firewall can run locally. It creates a local VPN on your device to block the apps you choose. No traffic is sent to any server, and the app never sends your data anywhere.
