Libor X
LIBOR no longer exists. Libor X brings together its successors on a single screen: SOFR and the Term SOFR curve, SONIA, SARON, TONAR — with history, a comparison across markets and a reading of the curve. On iPhone and iPad.
Free, for iPhone and iPad
Why it exists
The last LIBOR panels ended in 2023, and every major currency has moved to its new benchmark rate. Libor X lines them up: SOFR for the dollar — with the CME Term SOFR curve at 1, 3, 6 and 12 months — SONIA for sterling, SARON for the franc, TONAR for the yen. Looking for the euro? That lives in the Euribor X app.
The Markets screen
At the top are the four Term SOFR rates, one per card: value, change from the previous fixing, a three-month mini chart and the date. Below, the four overnight rates in compact rows — they barely move from one day to the next, which is why they have no chart in the list: tap the row and the full one opens. Each rate carries its own date: it’s normal for Term SOFR to be a day ahead of the overnight rates, as the administrators don’t all publish at the same time. And SARON can be negative: that’s not a mistake, Switzerland has long lived with rates below zero.
The Global screen
This is the comparison across markets. The USD term curve shows the Term SOFR curve from 1 to 12 months, overlaid on how it looked three months and a year ago, with a reading in plain words: if it rises, the market expects higher rates; if it is inverted, it is pricing in Fed cuts. The Rate ranking shows at a glance which currency pays the most today; One year, four currencies overlays the four overnight rates over the last twelve months.
The historical chart
Tap a card or a row and the historical series opens: ranges from one month to the full history available, and sliding your finger reads the exact value for each day. Below you’ll find the minimum, maximum, average and change over the period in basis points.
Free, and the ads can go
Since version 5.1 there is a single app, Libor X: free and complete, supported by Google AdMob ads — a banner and, now and then, a full-screen ad. And you can remove the ads: with an annual subscription, or a one-time purchase that lasts forever.
The old paid version is now called Libor Legacy: it keeps working but no longer gets updates. If you bought it, you can use Libor X without ads and without paying again — the support page explains how.
