# 周公解梦 vs 坚果百科

The clearest difference is in-app purchases: 周公解梦 at none against 坚果百科's 1. 周公解梦 also leads on device support and iOS requirement (7.0 vs 13.0). On price there is nothing between them.

Both are free to download. 坚果百科 sells 1 in-app purchase, starting at $0.99 per month. 周公解梦 asks for nothing beyond the download.
