Termux and SSH are not required. This is a native terminal IDE for Android that runs the Codex CLI natively on-device.

You can register an agent simply by writing in natural language, like "@agent send me a news summary every morning at 8 AM," and then Android's standard alarm system (setExactAndAllowWhileIdle) wakes the device with the screen off and executes it. You can register agents from the home screen widget's ASK field or by voice — you don't even need to open the app. Both scheduled execution and widget registration have been confirmed working on actual hardware (Galaxy Z Fold6). Note that precise alarm timing depends on OS specifications, so on devices with strong manufacturer-specific battery optimization, alarms may not fire.

The system includes execution memory that remembers previous run results and carries them forward to the next run, skill learning that saves successful procedures as recipes for automatic reuse, and fail-closed design that restricts tools to Codex and local-only during unattended execution.

It also supports local LLMs (llama.cpp), enabling fully offline AI use.

A non-engineer creative director built this using only a smartphone and conversations with AI. If you need additional features, fork it and modify it freely (GPLv3).
