# IGLOBE vs 知识星图

The clearest difference is in-app purchases: IGLOBE at none against 知识星图's 1. 知识星图's advantage is device support and iOS requirement (13.0 vs 15.0). On price there is nothing between them.

Both are free to download. 知识星图 sells 1 one-off in-app purchase. IGLOBE asks for nothing beyond the download.
