Currency converter and crypto prices on your new tab

Convert a set amount

Pick the currency you think in, then up to ten rows of currencies and coins against it. Set Amount to 100 and every currency row shows what 100 of your base is worth. Handy if you invoice a fixed sum or budget a trip.

It won’t replace a calculator. Changing the amount means a trip to settings, so for the odd one-off sum or a bit of arithmetic, a calculator widget parked right beside it will be quicker every time.

Crypto prices in the same table

24 coins sit alongside 31 currencies, each shown as "1 BTC = …" in your base currency. Coins pick their own precision by price, so bitcoin doesn’t get eight decimals and a tiny coin doesn’t round to zero. Currencies take a Decimals setting from 0 to 4.

An arrow and a percentage sit by every number. For a currency it’s the change since the last update; for a coin, the last 24 hours. A glance is enough.

Coin prices arrive in dollars and get converted, so switching the base currency re-prices them without a new request. Show inverse rates flips the currency rows when the other direction reads better.

Five designs

Classic (the table), Cards, Glass, Ticker and Minimal. A new widget comes up as Cards and opens the currency picker straight away. Ticker runs the rates as a scrolling line — trading-floor style.

There is no font size control. Resize the widget and the numbers follow.

Where the numbers come from

Currency rates come from Frankfurter every six hours, with open.er-api.com standing by, while coins come from CoinGecko every 15 minutes, with Binance as the spare. Two halves, each with a spare. They load separately, so one provider having a bad morning doesn’t blank the other.

The widget checks for fresh numbers every five minutes and skips that entirely while the tab sits hidden in the background.

Keep it small and off to one side. You want to notice a move, not stare at a ticker forty times a day.
