Verdict

The call

The clearest difference is rating: 不背单词 at 4.8 against 六级CET's 4.0. 不背单词 also leads on ratings volume (3.6K vs 1) and review sentiment (95% vs 75%). 六级CET's advantage is iOS requirement (11.0 vs 13.0). On price, update cadence, ads and in-app purchases there is nothing between them.
