Step 1 · Apps

Add your apps.

Connect Apple apps with a tap, the rest with a pasted token or a handle.

The Apps screen — connected apps and the catalog

Step 2 · Feed

One feed. Read it your way.

Tap a source and the feed takes that app's shape — Zerion becomes your wallet, Photos a grid.

Step 3 · See & act

It organizes itself. You act.

Home writes itself from your things, and every thing is one tap from its next action.

Home, composing itself

A thing's sheet — its next actions

Open a thing — act on it

Step 4 · Ask

Ask anything. Organize everything.

Ask a question, or say rename Work to Clients — it answers and reorganizes, all on your iPhone.
