There are plenty of other tools already that do this but hopefully this one adds some quality of life niceties such as dark mode and a mobile responsive design that seems nicer to use than the others out there.

Hope the colours look ok. I'm a colour blind person (deuteranomaly) and I've optimised it for what looks good to me. Am open to adding a mode in line with what regular vision people might prefer.

No frameworks used, vanilla JS. No sign ups. Data/state persistence is purely local storage.

Absolutely no commercial interest here. Built this purely for the love of it. Will forever be free.
