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.

CineMath▲8Hello HN! Over the last 15 years, I’ve worked as an AE/Editor, DIT, Colorist, Online Editor & Post Supervisor and based on my experience I've built a tool that I hope will be useful for some of you! It's a cinema calculator (aspect ratios, target speeds, target bitrates & more...) called CineMath and it's available for free download in the Apple App Store. I would be immensely grateful for any feedback and hope that it helps someone in their workflow!
