# American Heritage® Dictionary vs Collins Dictionary+Thesaurus

The clearest difference is rating: American Heritage® Dictionary at 4.7 against Collins Dictionary+Thesaurus's 3.9. American Heritage® Dictionary also leads on ratings volume (207 vs 15) and update cadence (every 2 months vs every 6 months). Collins Dictionary+Thesaurus's advantage is price ($6.99 vs $12.99) and iOS requirement (13.0 vs 15.0). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

American Heritage® Dictionary costs $12.99 and Collins Dictionary+Thesaurus $6.99 up front. American Heritage® Dictionary sells 1 one-off in-app purchase and Collins Dictionary+Thesaurus sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

American Heritage® Dictionary holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: American Heritage® Dictionary has 207 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 66% of American Heritage® Dictionary's written reviews are positive against 72% of Collins Dictionary+Thesaurus's, so the app with the better star average is not the one people write more warmly about.

American Heritage® Dictionary ships an update every 2 months, Collins Dictionary+Thesaurus every 6 months. Both last shipped on October 29, 2026.
