## What it is
An Android app that installs and runs OctoPrint on an old Android phone, turning it into a 3D printer control server without needing a Raspberry Pi. It connects to printers via USB OTG with a custom driver and can use the phone's camera for print monitoring.

## Use cases
- run octoprint on an old android phone
- control my 3d printer remotely without a raspberry pi
- monitor 3d prints with a phone camera
- connect a 3d printer to a phone over usb otg
- set up a cheap octoprint server
- ssh into octoprint on android

## When to choose
- you have a spare Android phone and no Raspberry Pi
- you want built-in camera monitoring without extra hardware
- you want a no-Linux-knowledge OctoPrint setup

## When to avoid
- your phone doesn't support simultaneous charging and USB OTG
- you need heavy-duty plugins or maximum reliability of a dedicated Pi
- you don't have an Android device to dedicate to printing
