Bootstrapping a side project into a profitable seven-figure business

Hi HN!I&#x27;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&#x27;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. So I built OffChess.OffChess is an iPhone&#x2F;Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in 1&#x2F;2&#x2F;3&#x2F;4&#x2F;5, tactics like pins&#x2F;forks&#x2F;skewers, or openings like Sicilian&#x2F;French, etc). You gain or lose points based on how you perform, so there&#x27;s a light rating system to keep things engaging.No accounts, no tracking, no monthly subscriptions, no internet required. Just pure, old-school tactical chess training, wherever you are.You can check out the iPhone&#x2F;iPad app at <a href="https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;chess-puzzles-offchess&#x2F;id6744736661?platform=iphone">https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;chess-puzzles-offchess&#x2F;id67447...</a> or the Android app at <a href="https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=com.offchess">https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=com.offchess</a>Would love feedback, bug reports, or suggestions.Thanks!

I built this because most Pomodoro timers felt too sterile.I wanted something that actually pulls you in with rain, brown noise, soft ASMR, and a few Middle Eastern tracks. Added animated backgrounds so it’s not just a blank screen.Runs fully in your browser. No accounts, no tracking, just open it and focus.If you give it a try or have ideas to make it better, I’d love to hear.
