Coming soon to the App Store
BiomboThe crypto tracker made for iPhone Duo
A crypto board that unfolds. Live prices and candlestick charts for Bitcoin, Ethereum and the top coins, laid out for every way you fold your iPhone Duo. Read-only, no account, nothing to connect.
Optimized for every iPhone Duo posture
Many apps just stretch when you open the iPhone Duo. Biombo changes its layout for each posture and snaps to the fold.
Inner display: up to four charts
Open it flat for one to four candlestick charts side by side, with dividers that snap to the fold, and a market map with the Fear & Greed index.
Cover display: your portfolio at a glance
Closed, your watchlist and portfolio fill the cover display, under a sky that follows the time of day.
Laptop and book mode: chart and details
Half-folded, the chart takes one half, and exchanges, 24-hour stats and your watchlist take the other.
Tent mode: a crypto ticker for your desk
Stand it up like a tent and the cover display becomes a crypto ticker for your desk, edge to edge.

Questions
- Is Biombo optimized for iPhone Duo?
- Yes. It was designed for iPhone Duo first: it uses the inner display, the cover display and the vertical bar, and changes layout in book, laptop and tent mode.
- Does it work on other iPhones and on iPad?
- Yes, on any iPhone and iPad with iOS 26 or later. The folding layouts show up on iPhone Duo.
- Is it a crypto exchange or a wallet?
- No. Biombo only shows market data. You can't buy, sell or connect an exchange, and it never asks for keys.
- Where does the data come from?
- From CoinGecko, through Biombo's server.
- When is it coming out?
- Soon, on the App Store. To hear when it's out, write to support@biomboapp.com.
