A fast, btop-style terminal UI for monitoring Android device and per-app performance in real time — over ADB, no root required.
- Per-core CPU — live usage bars and frequencies for every core
- App CPU & threads — top threads table with PID, CPU%, memory, core affinity
- Memory — used / free breakdown
- Battery & Power — level, charging state, doze / idle state
- Thermal — AP, SKIN, and battery temperatures with history
- Network — per-app and total Wi-Fi / mobile RX / TX with sparklines
- Jobs & Alarms — scheduled jobs and pending alarms for the selected app
- Device mode — monitor the whole device, or switch to a specific package
- Flicker-free rendering via
ratatuiwith async ADB collectors
- Rust 1.75+ (edition 2021)
- ADB in your
PATH - An Android device with USB debugging enabled (wired or over Wi-Fi)
