Verdict
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.
