Altimist, on the devices
you actually use.
One account, one shared context, and the same work waiting on every screen. The native apps are still being finished — pick your platform and we will write to you the day yours ships. Altimist in the browser works today.
What it looks like
The same work, sized to the screen
Image placeholder
Altimist for Mac in its own window on a real desktop — menu bar visible, native traffic lights, Studio open with the console. Should read unmistakably as a Mac app rather than a browser tab: rounded window, correct shadow, macOS wallpaper faintly visible behind.

iPhone in hand, Altimist open on the approvals view: one agent action awaiting a decision with Approve / Reject, and Face ID having just signed in. Portrait crop, dark theme.

Signed and notarised
Every desktop build will be signed and notarised for its platform, so you can verify it before installing if your policy requires it.
No password to set
First launch hands you to Altimist ID. You create a passkey; there is no password to choose, forget or have stolen.
Two channels
Stable by default, with an opt-in Beta channel. Waiting-list members get the Beta invitation first.
Get in line for the app — or just start in the browser.
Claiming a handle is free and takes a passkey. The desktop and mobile apps sign into the same account when they arrive.
