# Opcodes vs Verbum

The clearest difference is in-app purchases: Verbum at none against Opcodes's 1. Opcodes's advantage is ratings volume (6 vs 1) and iOS requirement (18.0 vs 26.2). On price, rating, ads and device support there is nothing between them.

Both are free to download. Opcodes sells 1 one-off in-app purchase. Verbum asks for nothing beyond the download.

Verbum holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Opcodes has 6 ratings behind it against 1, so its average is the more settled of the two.
