Verdict

The call

The clearest difference is in-app purchases: Sentiment at none against Kiwa's 3. Sentiment also leads on update cadence (fortnightly vs every 2 months) and iOS requirement (15.8.3 vs 18.6). Kiwa's advantage is ads (none vs shown). On price and device support there is nothing between them.
