Get the app
Everywhere you work
Sigma Domain works on your computer, your phone, and in any web browser. Your conversations, files and tools are saved to your account rather than to a device, so you can start on one and pick up on another.
Desktop apps
Sigma Domain on your Mac or PC
The desktop app opens in its own window with its own icon, so it isn't one tab among thirty and you can't lose your work by closing the wrong one. It's the same Sigma Domain you get in a browser, kept up to date automatically — you'll never be running an old version.

First launch on macOS
The app is ad-hoc signed but not yet notarized by Apple, so the first time you open it macOS will say "Sigma Domain is damaged and can't be opened." The file isn't damaged — that's just the wording macOS uses for un-notarized apps. To open it:
- Right-click Sigma Domain in Applications → Open → Open.
- Or run
xattr -cr "/Applications/Sigma Domain.app"in Terminal.
You only have to do this once.
First launch on Windows
SmartScreen will show "Windows protected your PC" because the installer is new and not yet widely downloaded. Click More info → Run anyway.
Phone apps
Sigma Domain on your phone
Android
The same tools, the same private storage, and the same shared conversations.
Sign in once and the same private database, files and connected tools are there on every device. A conversation open on your laptop mirrors live to your phone, so handing off mid-task doesn't mean starting over. See what each plan includes
Web
Or don't install anything
You don't need any of the apps. Sigma Domain works in any web browser — the same tools, the same files, the same conversations — and you can start using it as a guest without even making an account. The apps just give you an icon to tap and a window of your own; nothing is missing from the website.
