Traffik: Data Usage Monitor

Traffik is a data usage monitor and no-root firewall. See exactly how much mobile data and Wi-Fi data each app uses, watch your internet speed live in the status bar, and block the apps you don't want online. Everything is measured on your phone.

Android's own data usage screen shows you one total. Traffik shows you which app, on which network, at what time - and lets you stop it.

See Where Your Data Goes

- Data usage per app, split into Wi-Fi and mobile data for every app.

- Tap any app for upload vs download and a chart of its recent days.

- Sort and search to find the heavy users in seconds.

Live Internet Speed Meter

- Real-time upload and download speed right in your status bar.

- Turn the indicator on or off from a Quick Settings tile.

- Pro: more indicator styles, plus a live speed graph and the apps using data now, in the notification.

Data Plan, Limits and Alerts

- Set your monthly data plan with your own billing-cycle start day, and get a heads-up before you run out.

- Add a daily budget or a session limit to stay on pace.

- Give any app a daily data cap. Pro: caps of any size per day, week or billing cycle, on mobile data, Wi-Fi or both, and Data Saver that switches on by itself when you reach a limit or go abroad.

- Pro: prepaid plans and top-ups, night hours and apps your carrier doesn't count, and your carrier's daily reset time.

Block Apps From The Internet

- Stop any app from using mobile data, Wi-Fi, or both.

- Data Saver: only the apps you allow can use mobile data. Block everything: only your allowed apps get online.

- Pro: block apps on set days and times, or for as long as you like, and let a blocked app through for a while.

- Pro: profiles with their own rules that switch on by themselves at set times, on Wi-Fi, on mobile data or abroad.

- Pro: choose what new apps may use the moment they are installed.

- A local, on-device firewall built on Android's VpnService. No root needed. Android shows a key icon while it runs, but nothing leaves your phone: no server, no tunnel, no logging. It stays off until you switch it on.

History That Goes Back Further

- Android deletes data usage after about 3 months. Traffik keeps every finished day on your phone, so your history goes back further.

- Browse day by day, by month, or by billing cycle, and tap any day to see which apps used the most.

- This month and the 4 before it are always included. Pro opens every older month, CSV export, and backup and restore of your settings and Block rules.

Widgets, Tiles and Your Own Look

- A Data summary widget for your home screen.

- Pro: Data Saver, Quick switches and App switch widgets, Block all and Profile tiles, accent colours, app icons, and a pure black theme.

Private By Design

- Your data usage, your app list and your history never leave your phone, unless you export them yourself.

- No ads. No trackers. No analytics SDKs. No advertising ID. No account to create.

- No location permission. No contacts. No call or phone permissions.

Pro: Pay Once, Keep It Forever

Everything without the word Pro above works without paying. One purchase, never a subscription, unlocks all of Pro on your Google account. Want to support a one-person studio? The Supporter option gives you the same Pro plus a thank-you app icon.

Why Traffik Needs Each Permission

- Notifications: to show the live speed indicator and the alerts you turn on.

- Usage access (optional): to break usage down per app and keep history.

- VPN (VpnService): only so the optional firewall can run locally on your phone. Nothing is sent anywhere.
