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. So I built OffChess.

OffChess is an iPhone/Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in 1/2/3/4/5, tactics like pins/forks/skewers, or openings like Sicilian/French, etc). You gain or lose points based on how you perform, so there'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/iPad app at https://apps.apple.com/us/app/chess-puzzles-offchess/id67447... or the Android app at https://play.google.com/store/apps/details?id=com.offchess

Would love feedback, bug reports, or suggestions.

Thanks!

Note that the discussion continues in the collapsed comment by tomhow: https://news.ycombinator.com/item?id=44499848

It says "stub for offtopicness" but, skimming them, literally all comments are on-topic. Not all substantial ('very nice app', 'whats the tech stack?') but a lot of other comments are a normal amount of substantial and also in there... I don't get it, but note that you can expand that subthread

I posted this

``` Hi ,Congrats on the launch. I built a free iOS app also which has chess puzzles.

Would appreciate feedback. ```

Not sure if that's why it was moved to `stub for off topicness`. I wonder if it is some kind of categorisation logic based on text.

Why would you in 2025 only build for iOS?

This was a swift app. I wanted a bit more native feel and didn't go for react native.
