# VOA商务美语 vs 有书趣

The clearest difference is in-app purchases: 有书趣 at none against VOA商务美语's 1. 有书趣 also leads on update cadence (weekly vs every 4 months). VOA商务美语's advantage is ads (none vs shown) and iOS requirement (9.0 vs 12.0). On price and device support there is nothing between them.

Both are free to download. VOA商务美语 sells 1 one-off in-app purchase. 有书趣 asks for nothing beyond the download.

VOA商务美语 ships an update every 4 months, 有书趣 weekly. The most recent releases landed on October 15, 2026 and October 20, 2026 respectively.
