# 易呗背单词 vs 词力派

The clearest difference is in-app purchases: 易呗背单词 at none against 词力派's 8. 易呗背单词 also leads on ratings volume (10 vs 2) and iOS requirement (9.0 vs 13.0). 词力派's advantage is update cadence (every 4 days vs every 15 months). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. 词力派 sells 8 one-off in-app purchases. 易呗背单词 asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for 易呗背单词 against 5.0 for 词力派. That said, the two scores are not equally well evidenced: 易呗背单词 has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

易呗背单词 ships an update every 15 months, 词力派 every 4 days. The most recent releases landed on June 3, 2026 and July 8, 2026 respectively.
