Numpad: https://numpad.io/ https://numpad.io/ It's a web-based notepad calculator, which means it's a notes app but it can evaluate inline calculations like ``` £300 in USD + 20% 09:00 to 18:30 - 45 minutes ``` I wrote the core of the calculator a few years ago, and I've just launched a big rewrite that supports * document syncing * offline editing * markdown formatting * PDF and HTML exports * autocomplete * vim mode Happy to hear feedback :)
