Download the app and check device compatibility
By Landon McCoy · Updated September 10, 2026
Use the Chaos Audio app for both Stratus and Nimbus. Download it through the official Apple App Store or Google Play listing.
Find the official app
The store listing is the authority for whether the current public release supports your device. The app is free to download; optional effects and additional AI builds may cost extra.

Phones, tablets, and the latest app
The latest app code supports iOS/iPadOS 15 or newer and Android 8 or newer, with tablet layout improvements. These are preview software requirements, not a guarantee for every device or public store version. Do not confuse Android’s target API level with its minimum supported OS.
Using a computer
You can use FX Builder in your browser without installing the mobile app. Mac availability of the mobile app depends on its App Store listing and your hardware; this guide does not promise a native Windows or Mac editor.
