# 易呗背单词 vs 试题库

The clearest difference is update cadence: 试题库 at every 3 months against 易呗背单词's every 15 months. 易呗背单词's advantage is device support (3 vs 1) and iOS requirement (9.0 vs 17). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

易呗背单词 ships an update every 15 months, 试题库 every 3 months. The most recent releases landed on June 3, 2026 and September 13, 2026 respectively.
