Hi HN! I'm the developer of rdx, a mildly popular ad-free, privacy and user friendly Reddit client. This time, I made something for a very specific use case: solving chess puzzles with no internet. Why? Well, my Wi-Fi is terrible in the bathroom—and that's where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction.

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…
