CineMath
Hello 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!

Datafilm2021 · withframes.com · ▲84Frames is a simple app for analog film photographers to log shot details like camera, lens, film stock, exposure settings, and notes while shooting. Later, it can embed this metadata into scanned JPEGs to keep the technical and creative context of each frame. The iPhone app lets you record notes in the field, and the companion Mac app helps attach metadata to your digital scans. There's no cloud storage — everything stays local. The iPhone app is free, and the Mac app has a 7-day trial. I built Frames because I wanted a lightweight, privacy-first tool to bridge the gap between analog…

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
