Traffik: Data Usage Monitor Live

Traffik is a data usage monitor that shows exactly how much mobile data and Wi-Fi data your phone uses, which apps are spending it, and how fast your connection is right now. Everything is measured on your device. Android's built-in 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 - Per-app data usage, split into Wi-Fi and mobile for every app. - Tap any app for upload vs download and a recent-days chart. - Sort and search to find the heavy users in seconds. Live Internet Speed - A real-time internet speed meter for upload and download, right in your status bar. - Switch the indicator on or off from a Quick Settings tile. - Several clean, minimal indicator styles. Data Limits That Warn You In Time - Set a monthly data plan with your own billing-cycle start day. - Get a calm heads-up before you run out, not after. - Add a daily budget or a short session limit to stay on pace. Keep Any App On Wi-Fi Only - Stop any app from using mobile data, Wi-Fi, or both. - Turn on Data Saver so only the apps you allow can touch mobile data. - Works as a local, on-device firewall built on Android's VpnService. 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. Usage History You Never Lose - Browse your data usage day by day, by month, or by billing cycle. - Tap any day to see that day's top apps. - Export your history to CSV whenever you want it. Private By Design - Your data usage never leaves your phone. - No ads. No trackers. No analytics. No advertising ID. No account to create. - No location permission. No contacts. No call or phone permissions. - Traffik reads your device's own data counters and nothing else. Buy Once, Yours Forever Everything above is free, and there are no ads anywhere. One single purchase, never a subscription, unlocks custom firewall profiles, per-app schedules, per-app data caps, premium indicator styles, an AMOLED black theme, CSV export, a home-screen widget, and automatic Data Saver while roaming. Built For Modern Android Material You design that follows your light or dark theme and your wallpaper colours. Fast, light, and careful with your battery. Translated into dozens of languages. Why Traffik Needs Each Permission - Notifications: to show the live speed indicator. - 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. Made by Selenium Studio.
