# Papyrus vs Open Hub

The clearest difference is in-app purchases: Papyrus at none against Open Hub's 1. On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Open Hub sells 1 one-off in-app purchase. Papyrus asks for nothing beyond the download.
