Two generations of offline Apple chess apps

For years, Shredder on iPhone and iPad was the standard answer whenever someone asked for a serious offline chess app without free-to-play clutter. It earned that reputation by shipping a real engine and charging an honest price with zero ads.

Brass Pawn carries that same offline, zero-ad ethic forward into modern SwiftUI across iPhone, iPad and Apple Silicon Mac. Where Shredder centres on one classic engine and a 1,000-puzzle pack, Brass Pawn compiles both Stockfish 18 and Reckless 0.10 locally, expands the tactics set to 14,351 motif-tagged positions, adds 116 quiet positional exercises and 900 decisive master games, and explains mistakes using win probability rather than raw centipawn swings.

Free play vs paid-upfront download

With Shredder iOS, you pay upfront before playing your first game, and desktop Shredder for macOS is a separate purchase. Brass Pawn lets you install on iPhone, iPad and Mac for $0, play unlimited coached engine games and Game Center matches forever, and pay $3.99/month or $39.99 once only if you want unlimited daily training drills.

Honest boundaries

When Shredder Chess is the better fit

  • Shredder’s mobile app is a lower single upfront price (~$7.99–$9.99 on iOS alone) if you only want basic mobile play and 1,000 puzzles without Mac sync or 14,351 tactics — though playing against the engine in Brass Pawn is $0.
  • Desktop Deep Shredder supports external UCI engines, opening book editing and PGN file databases that Brass Pawn does not target.
  • Shredder also ships Android and Windows versions; Brass Pawn is Apple-native.

Frequently asked questions

Is Stockfish 18 in Brass Pawn stronger than mobile Shredder?
At full strength, Stockfish 18 is the top-rated chess engine in the world and stronger than any human or classic commercial mobile engine. More importantly for training, Brass Pawn uses Stockfish’s UCI_Elo search-depth limiting so you can set human-scaled opposition from roughly 1400 upward.
Why does Brass Pawn include Reckless 0.10 alongside Stockfish 18?
Even elite engines evaluate imbalanced positions differently. Including Reckless 0.10 gives you an instant offline second opinion in Settings when analysing a sharp sacrifice or fortress, though Reckless plays at full strength only.
Does Brass Pawn work on Airplane Mode like Shredder?
Yes. Both engines, all 14,351 tactics puzzles, 116 positional exercises, 15 endgame drills, 1,624 Guess the Elo games and 900 Watch games are bundled locally and need zero internet access.
Does Brass Pawn support Mac as well as iPhone and iPad?
Yes. Brass Pawn ships natively for iOS 17+, iPadOS 17+ and macOS 14+ under a single App Store listing.
