Currency by SOBE

A currency converter that shows the official rate of each currency's central bank beside the market rate, and charts the gap between them. 66 central banks. Ready for iPhone Duo since version 1.2 (October 14, 2026): unfolded, the list stays on the left and the chart opens on the right.

16-second screen recording of the unfolded iPhone Duo in the Xcode simulator: the chart follows the list while the converter stays on screen. Download MP4, 1920×1350, 13 MB.

In one paragraph

Currency by SOBE converts one amount into your whole list at once: world currencies, crypto, precious and industrial metals, oil and gas. Next to each market rate it shows the official reference rate of the currency's own central bank, from 66 banks, with a chart of both and the gap between them. On iPhone Duo and iPad the screen splits into the list and the chart; the app also runs on Apple Watch, on Mac with Apple silicon and on Android. Free, with an optional Pro subscription. No ads and no account.

On iPhone Duo

Unfolded, the screen splits along the fold: the converter and your list on one half, the chart and the comparison with the central bank on the other.
The chart opens beside the list instead of on top of it, so the converter never leaves the screen.
Folded, it is the familiar one-column app.
The same split layout works on iPad.
Built and tested in the Xcode Duo simulator ahead of the October 23 launch.
