Verdict

The call

The clearest difference is in-app purchases: ClassBuddy at none against 不背单词's 100. ClassBuddy also leads on update cadence (every 4 days vs every 3 weeks). 不背单词's advantage is ratings volume (3.6K vs 6) and iOS requirement (13.0 vs 17.0). On price, rating, review sentiment and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

UpkeepUpdate frequency

不背单词 ships an update every 3 weeks, ClassBuddy every 4 days. Both last shipped on October 24, 2026.
