# Blocus vs Kairos

The clearest difference is rating: Kairos at 5.0 against Blocus's 4.5. Blocus's advantage is ratings volume (226 vs 1) and update cadence (every 3 days vs weekly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Blocus sells 10 in-app purchases, starting at $9.99 per month and Kairos sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Kairos holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Blocus has 226 ratings behind it against 1, so its average is the more settled of the two.

Blocus ships an update every 3 days, Kairos weekly. Both last shipped on November 5, 2026.
