Verdict

The call

The clearest difference is in-app purchases: 易呗背单词 at none against 不背单词's 10. 易呗背单词 also leads on iOS requirement (9.0 vs 13.0). 不背单词's advantage is update cadence (every 3 weeks vs every 15 months) and ratings volume (3.6K vs 10). On price, rating, review sentiment and ads there is nothing between them.
