GarageBand

GarageBand on the inner screen: fills the whole inner screen. It gets 2,853 × 2,007 pixels, drawn to the geometry measured in the simulator.

How we know

How we decide

  1. Developer says so

    The notes for version 2.3.20 say:

    • Adds support for iPhone Duo • This update includes stability improvements and bug fixes

  2. Made by Apple

    Version 2.3.20 came out after the iOS 27.1 SDK, and Apple builds its own apps with its latest SDK.

Not what you see? Report “Ready” as incorrect

This page says version 2.3.20 fills the whole inner screen. If that’s not what GarageBand looks like on your iPhone Duo’s inner screen, tell us. It changes to “Not ready” once three people report it, at least one with a screenshot.

Optional, but it’s the proof that lets reports change the answer. Your screenshot stays on your device: we only send a tiny grayscale copy to check it.
