DataDetector

android tells you how much data you used. i wanted to know where it went.

On-device network monitoring: per-app consumption, live speeds, usage trends and data budgets, without sending your usage somewhere else.

React Native → Kotlin → Android APIs → SQLite

below the React Native surface

Native Kotlin integrates UsageStatsManager, TrafficStats, foreground services and home-screen widgets. JSI-based SQLite access keeps the usage history local.

Heatmaps, 7-day and 30-day trends, monthly comparisons and a persistent speed notification make the numbers useful.
