Things that
change

Twelve apps, one method: take a number that moves — a score, a fixing, a queue at the tunnel, a stock, a ranking — and make it readable in two seconds.

The apps · live data

Each row opens its app’s page. The rows with live figures show the same data as the apps.

Just open them

Three single pages, hosted here: nothing to install, no account. Open the link and the maths is already done.

Enter the ticker and your purchase details: see what the investment returns and how much of it comes from the change in price and how much from the change in exchange rate.

The official series side by side: daily Euribor from EMMI and ECB rates from the SDMX API, with history and changes over a period of your choice.

Euribor Weekly

Every Monday morning, one email: the week’s Euribor rates, how much they moved and what changes for the payment on a variable-rate mortgage. Free. The first issue comes out on Monday 19 October 2026.

Your first name, last name and email are used only to send you the newsletter. You’ll get an email to confirm, and you can unsubscribe with one click from any issue. Privacy.

Sport

The sums you do while staring at a ranking: move the results and see how it changes.

Sinner is out injured and Zverev is heading for number 1: pick his results in the remaining tournaments and see in which week he overtakes.

Games

Four arcade classics, one per page: add them to your phone’s Home Screen and they work offline too.

’80s shoot ’em up: diving squadrons and a laser that powers up, from single to double to triple.

All games

The arcade classic. Against the computer, on three levels that change the way you play, or two players on the same screen.

All games

The well, the seven pieces, the lines to clear. Ghost piece, preview and hold, just like the arcade cabinets.

All games

The workshop

The data doesn’t update itself: the state of the Gotthard tunnel is checked every five minutes, and the fixings arrive on the same day they are published. It’s the same data the apps use.

Everything underneath these apps lives in a single repo: github.com/fbacchin/app.
