# Primus Chess Lite vs Chess Log

The clearest difference is update cadence: Chess Log at every 6 weeks against Primus Chess Lite's every 9 months. Chess Log also leads on review sentiment (100% vs 79%). Primus Chess Lite's advantage is rating (4.3 vs 4.0) and ratings volume (23 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Primus Chess Lite holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Primus Chess Lite has 23 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 79% of Primus Chess Lite's written reviews are positive against 100% of Chess Log's, so the app with the better star average is not the one people write more warmly about.

Primus Chess Lite ships an update every 9 months, Chess Log every 6 weeks. The most recent releases landed on October 21, 2026 and October 9, 2026 respectively.
