The iPhone app is in TestFlight preview. Screens below come from the preview build with a demo account, so the numbers are illustrative. Layout and names match the build; details may still move before release.

Five places to be
One tab bar across the bottom: Home, Search, Chat (the Donut mark in the middle), Signals, and Portfolio. Activity lives beside Signals as a second tab.Home
Five shortcuts across the top (Recap, Signals, Automations, News, New), your balance underneath, and your watchlist below. Tap a headline in News and it arrives in the chat composer already framed as a question: What does this mean for my portfolio?
Signals and Activity
Signals is what the market is doing: a daily brief at the top, then signal cards, each with a direction. Activity is what D0 is doing: every fill, alert, failed order, and transfer, timestamped. Failures are logged in the same list as fills.

Chat
Describe what you want in plain English. For an automation, D0 asks what it needs (topics, priorities, how the briefing should read), then states the rule back: cadence, scope, delivery. Every automation then shows its schedule and state on one sheet.


Recap
Today’s recap says what moved your book, what drove it, and what to watch next, with share, ask d0, and signals at the bottom.
Portfolio
Spot & DeFi, Donut Perps, Hyperliquid Perps, and Polymarket, totalled in one place, with Deposit / Withdraw / Transfer / History above the accounts and a 24h / 7d / 30d / All range switch.
