Verdict
The clearest difference is in-app purchases: Nextcloud Calendar at none against KairoProject's 2. Nextcloud Calendar also leads on iOS requirement (16.4 vs 18.6). KairoProject's advantage is update cadence (every 5 days vs every 2 weeks). On price, ads and device support there is nothing between them.
