Verdict
The clearest difference is rating: Dictionary. at 4.8 against Thesaurus's 1.0. Dictionary. also leads on ratings volume (15K vs 1). Thesaurus's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence, device support and iOS requirement 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. Dictionary. sells 1 one-off in-app purchase. Thesaurus asks for nothing beyond the download.
Dictionary. holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Dictionary. has 15K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 91% of Dictionary.'s written reviews are positive against 100% of Thesaurus's, so the app with the better star average is not the one people write more warmly about.
Dictionary. ships an update every 3 months, Thesaurus every 2 months. The most recent releases landed on September 25, 2026 and August 14, 2026 respectively.
