Verdict
The clearest difference is price: Dictionary.com at Free against Thesaurus App's $0.99. Dictionary.com also leads on rating (4.8 vs 1.0) and update cadence (monthly vs every 8 months). Thesaurus App's advantage is in-app purchases (none vs 9) and ads (none vs shown). On review sentiment 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
Dictionary.com is free to download; Thesaurus App costs $0.99 up front. Dictionary.com sells 9 one-off in-app purchases. Thesaurus App asks for nothing beyond the download.
Dictionary.com holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Dictionary.com has 328K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 29% of Thesaurus App's written reviews are positive against 26% of Dictionary.com's, so the app with the better star average is not the one people write more warmly about.
Thesaurus App ships an update every 8 months, Dictionary.com monthly. The most recent releases landed on September 21, 2026 and September 25, 2026 respectively.
