# Stockfish Chess Analysis vs Tri

The clearest difference is review sentiment: Tri at 100% against Stockfish Chess Analysis's 14%. Tri also leads on rating (5.0 vs 4.4) and monetization model (free vs free with in-app purchases). Stockfish Chess Analysis's advantage is ratings volume (81 vs 3) and iOS requirement (15.0 vs 17.5). On price, update cadence, ads and in-app purchases 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 Tri sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Tri 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 81 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 14% of Stockfish Chess Analysis's written reviews are positive against 100% of Tri's.
