Clipbox Traffic Checker

Clipbox Traffic Checker is a data-usage monitoring extension that helps you track mobile and Wi‑Fi traffic. It shows traffic volume, provides historical graphs, the latest values, and the ability to switch between mobile and Wi‑Fi data. The widget makes it easy to view current usage at a glance, helping you stay within monthly limits and avoid overage across major carriers like Docomo, SoftBank, and au.

Key features include data tracking, remaining capacity with numeric and gauge, history graphs by day/month/year, latest traffic figures, average traffic, and adjustable usage limits. It also supports push notifications at 50%, 30%, and 10%, date resets, mid-month usage adjustment, FAQ and inquiry forms, and a data reset function. The app is free to use (ads supported).
