# WordBook (Universal) vs Dictionary and Thesaurus Pro

The clearest difference is price: WordBook (Universal) at $2.99 against Dictionary and Thesaurus Pro's $9.99. WordBook (Universal) also leads on iOS requirement (7.0 vs 13.0). Dictionary and Thesaurus Pro's advantage is ratings volume (2.6K vs 275). On rating, review sentiment, update cadence and ads there is nothing between them.

WordBook (Universal) costs $2.99 and Dictionary and Thesaurus Pro $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Dictionary and Thesaurus Pro holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Dictionary and Thesaurus Pro has 2.6K ratings behind it against 275, so its average is the more settled of the two. Written reviews complicate that: 88% of WordBook (Universal)'s written reviews are positive against 87% of Dictionary and Thesaurus Pro's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 4 months. Both last shipped on November 6, 2026.
