Verdict
The clearest difference is ads: Oxford Dictionary & Thesaurus at none against Merriam's shown. Oxford Dictionary & Thesaurus also leads on update cadence (monthly vs every 3 months). Merriam's advantage is review sentiment (83% vs 52%) and rating (4.8 vs 4.6). On price, in-app purchases, monetization model and chart position 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
Both are free to download. Merriam sells 4 in-app purchases, starting at $1.79 per month and Oxford Dictionary & Thesaurus sells 8 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Merriam holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Merriam has 328K ratings behind it against 29K, so its average is the more settled of the two. Written reviews point the same way: 83% of Merriam's written reviews are positive against 52% of Oxford Dictionary & Thesaurus's.
Merriam ships an update every 3 months, Oxford Dictionary & Thesaurus monthly. Both last shipped on September 24, 2026.
