# 學測單字+ vs 背著句子跑

The clearest difference is ads: 背著句子跑 at none against 學測單字+'s shown. 背著句子跑 also leads on update cadence (weekly vs every 3 months). 學測單字+'s advantage is device support (3 vs 1) and iOS requirement (15.1 vs 26.0). On price and in-app purchases there is nothing between them.

Both are free to download. 學測單字+ sells 2 in-app purchases, starting at $2.99 per month and 背著句子跑 sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

學測單字+ ships an update every 3 months, 背著句子跑 weekly. The most recent releases landed on October 5, 2026 and October 4, 2026 respectively.
