this exists because I got tired of using that kraken calculator! glad you find it useful too.
it makes a single request to the public kraken api for btc/usd price.
This looks identical in function and source (Kraken) to this calculator

But your version doesn’t have all the extra 3rd party connections or HTML5 canvas data extraction.
Well done! Bookmarked!

It works well by turning it into an icon on iOS (dynamic web app or link they call it?) except the numbers keyboard doesn’t give me the ability to add a decimal point. Maybe an iOS quirk
It’s an iOS thing… I went round and round with it and ultimately compromised for number pad without the decimal. there’s a pretty comprehensive stackoverflow post I found by searching “best settings for HTML number input for moble” that details it.
