No, and you will likely never be able to. GooTool was written in Java for maximum portability, but Apple have decided not to support Java on the iPhone.

However, if you have jailbroken your iPhone and installed the SSH server, you can run GooTool on your desktop computer and write a custom World of Goo to your iPhone using SFTP.

Jailbreaking your iPhone is unsupported and possibly in violation of your agreement with Apple. Proceed at your own risk.

Initial Setup

  • Jailbreak your iPhone. You will have to figure out how to do this on your own.
  • Install "openssh" using Cydia.
  • Purchase World of Goo from the App Store. GooTool will never support illegal copies of World of Goo.
  • Run GooTool on your desktop computer. On the File menu, choose iPhone -> Prepare.
  • Enter the IP address of your iPhone and the root password (default: alpine).
  • GooTool downloads World of Goo from your iPhone and saves it locally on your computer to speed up future builds. This will take several minutes.

Building your World of Goo

  • On the File menu, choose iPhone -> Deploy.
  • Enter the IP address of your iPhone and the root password (default: alpine).
  • A custom World of Goo will be built on your iPhone. This takes a very long time the first time you do it.


  • Make sure your iPhone is awake while GooTool is accessing it.. Turn off auto-lock, or touch the screen every 30 seconds while GooTool is preparing or deploying to your iPhone.
  • Do not run Custom World of Goo on your iPhone while GooTool is running, or if an error occured when building your World.
  • Avoid frequently rebuilding your World of Goo, to reduce wear on your iPhone's Flash memory.
  • The addins installed on your iPhone are the same addins selected for your desktop copy, on the Addins tab.
  • Make sure you are using your Wifi connection and IP address to avoid massive data charges and slow speeds over the cellular network.
