Verdict
The clearest difference is price: WordBook (Universal) at $2.99 against Merriam's $9.99. WordBook (Universal) also leads on iOS requirement (7.0 vs 15.0). Merriam's advantage is ratings volume (22K vs 275) and chart position (#10 vs #187). On rating, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
WordBook (Universal) costs $2.99 and Merriam $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Merriam holds the better App Store score, 4.8 against 4.7. That said, the two scores are not equally well evidenced: Merriam has 22K 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 82% of Merriam's, so the app with the better star average is not the one people write more warmly about.
WordBook (Universal) ships an update every 4 months, Merriam every 5 months. The most recent releases landed on November 1, 2026 and November 5, 2026 respectively.
