Data Usage Monitor & Firewall

Stop apps from eating your mobile data. Data Usage Monitor shows exactly which apps use your data, warns you before you run out, and blocks any app's mobile data or Wi-Fi with one tap. No root needed.

BLOCK APPS FROM USING DATA
- Per-app firewall: block an app on mobile data, on Wi-Fi, or both
- No root required. Uses Android's local VPN, so your traffic never leaves your phone
- Ask to block new apps as soon as you install them
- Roaming mode: while abroad, only the apps you choose can use mobile data

NEVER GO OVER YOUR DATA PLAN
- Set your plan: monthly, weekly, daily or prepaid bundles (3, 7, 15, 30 days)
- Alerts at 50%, 80% and 100% of your data limit
- Auto-block: stop all mobile data automatically when you reach your limit
- Daily data limits per app. YouTube, TikTok or games get blocked for the rest of the day once they hit your limit
- See how much data is left, days to renewal and a safe amount per day

SEE WHERE YOUR DATA GOES
- Mobile data vs Wi-Fi usage for every app
- Top data-hungry apps this cycle
- Data meter in the status bar: today's mobile data at a glance
- Home-screen widget with today's usage, plan left and a firewall switch
- Evening summary of your data and screen time

SCREEN TIME TOO
- Daily screen time per app
- Weekly report with trends and your most-used apps

PRIVATE BY DESIGN
- Usage stats are read and processed on your device
- No account and no sign-up
- The firewall is a local VPN on your phone. It does not route your traffic through any server and does not log what you browse

WHY PEOPLE USE IT
- Prepaid users who want their bundle to last
- Anyone who keeps running out of data before the month ends
- Parents limiting video and game apps on mobile data
- Travellers avoiding roaming charges

HOW IT WORKS
1. Allow Usage Access so the app can read data and screen-time stats
2. Set your data plan (optional)
3. Turn on the firewall and tap the phone or Wi-Fi button next to any app

PERMISSIONS
- Usage Access: to read per-app data and screen time on your device
- VPN: to run the on-device firewall that blocks apps you choose. No external VPN server is used
- Notifications: for data alerts, the status-bar meter and the firewall status

Data Usage Monitor contains ads. Data counts come from Android and can differ slightly from your carrier's.
