# Kana vs CALC~blocks

The clearest difference is rating: Kana at 5.0 against CALC~blocks's 4.0. Kana also leads on ads (none vs shown) and monetization model (free vs ad-supported). CALC~blocks's advantage is update cadence (every 3 weeks vs every 16 months) and review sentiment (65% vs 50%). On price, ratings volume, in-app purchases and device support there is nothing between them.

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

Kana holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 2 and 4 respectively. Written reviews complicate that: 50% of Kana's written reviews are positive against 65% of CALC~blocks's, so the app with the better star average is not the one people write more warmly about.

Kana ships an update every 16 months, CALC~blocks every 3 weeks. The most recent releases landed on October 26, 2026 and October 21, 2026 respectively.
