# Stockfish Chess Analysis vs Chess Engine

The clearest difference is rating: Chess Engine at 5.0 against Stockfish Chess Analysis's 4.4. Chess Engine also leads on update cadence (every 5 days vs fortnightly). Stockfish Chess Analysis's advantage is ratings volume (77 vs 2) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stockfish Chess Analysis sells 3 in-app purchases, starting at $8.99 per 7 days and Chess Engine sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Chess Engine holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Stockfish Chess Analysis has 77 ratings behind it against 2, so its average is the more settled of the two.

Stockfish Chess Analysis ships an update fortnightly, Chess Engine every 5 days. The most recent releases landed on October 19, 2026 and October 11, 2026 respectively.
