Hey folks ,
You might know me as the dev behind RDX, the completely free, open-source, ad-free, privacy friendly Reddit client. RDX has hit 100K+ downloads on both app stores combined with apple having the lion's share of it.

This time, I built something different—but still in the same spirit of privacy, simplicity, and it works without needing an internet connection.

Well, my Wi-Fi is terrible in the bathroom, and that's where I, like everyone, do some of my best thinking. I tried printing out paper chess 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/id6744736661?platform=iphone or the Android app at https://play.google.com/store/apps/details?id=com.offchess

You get 7 puzzles free every day at midnight. if you need more than that there is a one time purchase(not a subscription) of $3.99 that unlocks all 100k puzzles, forever.

Folks over at hackernews loved it so I decided to post it here on !technology, given that a lot of people on lemmy and specifically this space use my other app RDX.

Would love feedback, bug reports, or suggestions.

Thanks!
