ADB Captain: On-Device ADB Tool

ADB Captain is a development utility by eatenlamp that lets you execute ADB shell commands directly on an Android device through Shizuku, without a computer or root access. The usual obstacle when working with ADB is that it requires a host machine, a USB connection or a paired wireless session, and a desktop terminal; this app removes that dependency by routing shell access through Shizuku, which grants the necessary privileges on the device itself. Version 1.6 was updated on 2026-10-22, the first release dates to 2026-09-20, the package is 28 MB, and it requires Android 7.0 or newer. The project is licensed under AGPL-3.0-or-later and is offered free of charge. It bundles a terminal, a debugging workspace, package inspection, process management, logcat, and wireless ADB controls into one interface.

Key features

• Terminal supporting commands such as pm, am, dumpsys, settings and input, with several simultaneous sessions, autocomplete drawn from command history, recency-grouped history and pinnable commands
• Debugging workspace with bug report ZIP export, timed sessions that buffer logs while you reproduce a crash, saved macros for command chains, and crash logs grouped per app with full stack traces
• App list separating user and system packages, each with a plain safety rating, plus an inspector for activities, services, receivers and providers and a manual intent launcher
• Process table showing PID, parent, user and memory, searchable, with force-stop available on any row
• Device information screen covering model, Android version, battery and connection status, with reboot and screenshot actions
• Wireless ADB pairing and connection over Wi-Fi with shell access, saved devices, one-tap reconnect and optional auto-reconnect
• Logcat with level and text filtering, front-app following, saving the visible output to a file and sharing it as Markdown
• Sideloading of APKs from storage and quick tools for screen recording, Wi-Fi, Bluetooth or airplane mode toggling, text entry and opening links
• Material 3 Expressive interface with light or dark theme, five accent palettes or system-driven Material You colors

How to install

1. Tap the download button on this page to obtain the APK file.
2. When Android prompts you, allow your browser or file manager to install apps by enabling the Install unknown apps setting for that app.
3. Open the downloaded APK file; the package is 28 MB.
4. Tap Install and wait for the process to finish.
5. Open the app; it requires Android 7.0 or newer.

This app suits Android developers, power users and testers who already understand ADB and want to run shell commands, capture logs, inspect installed packages or manage processes while away from a desktop. It is also relevant for anyone doing wireless debugging on a second device, provided Shizuku is set up and the user is comfortable with command-line work rather than a purely graphical workflow.

Set up Shizuku before first use, since every privileged function depends on it. Pin frequently used commands and save macros for repetitive chains, and rely on the safety ratings in the app list before disabling or removing any package. When reporting a crash, the timed session and Markdown log export keep the evidence in a shareable form.

ADB Captain consolidates the common ADB tasks into a single on-device interface backed by Shizuku, with a scope that covers terminal work, logging, package inspection and wireless connections. It is a practical choice for users who know what they are doing with shell commands, and it stays free, ad-free and open source under AGPL-3.0-or-later.
