I launched NumPad v1 on here a few years ago, and back then it wasn't much more than a thin CodeMirror wrapper around the calculator engine I'd written. Now I've rewritten it as a PWA that supports multiple documents, persists them to IndexedDB, and has a syncing service for paying customers. Syncing is handled by Automerge[1] under the hood, which should make it relatively easy to get document sharing working too. [1] https://automerge.org/

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:…

Here's something different than your usual fare: A physical keypad that lets you directly type math! Ever tried typing mathematical equations in your code IDE, email, or on Slack? You might know it can be tricky. Mathpad solves this with dedicated keys for Greek letters, calculus symbols, and more. Press the ∫ key and get ∫, in any application that accepts text.
