# 开源中国 vs Crew

The clearest difference is rating: Crew at 4.4 against 开源中国's 1.8. Crew also leads on review sentiment (67% vs 33%) and ratings volume (64 vs 5). 开源中国's advantage is in-app purchases (none vs 7) and iOS requirement (9.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. Crew sells 7 in-app purchases, starting at $1.99 per month. 开源中国 asks for nothing beyond the download.

Crew holds the better App Store score, 4.4 against 1.8. That said, the two scores are not equally well evidenced: Crew has 64 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 33% of 开源中国's written reviews are positive against 67% of Crew's.

开源中国 ships an update every 3 weeks, Crew every 10 days. The most recent releases landed on July 3, 2026 and September 14, 2026 respectively.
