    Hello HN, I've created a new Sudoku app for iOS and Android that prioritizes simplicity and privacy. It's free to download and use, and I'd be grateful for any feedback or suggestions. Features: > 4 difficulty levels, accessible at any time > No personal data collection of any kind > Clean, minimalistic design that focuses on the game > Takes up significantly less space than other popular apps (by a factor of about 10x) > Minimal use of advertisements I was frustrated by how many of the popular Sudoku apps feel excessively over-engineered, consume a lot of storage space and some that even…

  • 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…
