   I made a web-based notepad with a built in unit calculator▲488

   Hi HN It also supports percentages, dates and variables. I've been working on this alone for a few years now, so would love to get some feedback.

   Figr.app – a multi-user, notepad style calculator (desktop app)▲275

   Hi all, just posting an update to my previous Show HN, where I announced a side-project I worked on which was a (web version) of a multi-user, notepad style calculator: https://news.ycombinator.com/item?id=31817997 After a couple of user requests (and having a good think about it) I decided to migrate the web UI to create a Mac and Windows desktop app. After using it a little bit, I feel this is a much better experience than the webapp, and reduces a lot of the friction if I wanted to run a few small calculations. You can find the download links below:…
