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 HN Just sharing a small tool I built: https://cbmcalc.com It calculates CBM (cubic meters) for shipping cartons, pallets, or multiple boxes. I made it because most CBM calculators online are too simple and some couldn't add multi items. This one is simple and kinda works on mobile too Would love any feedback!
