Verdict
The clearest difference is review sentiment: Chrono Rainbow at 100% against 日本姓氏語源辞典's 0%. Chrono Rainbow also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 14 months). 日本姓氏語源辞典's advantage is in-app purchases (none vs 2) and iOS requirement (16.0 vs 18.5). On price and device support there is nothing between them.
