Verdict

The call

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.

Both are free to download. Dictionary. sells 1 one-off in-app purchase. Thesaurus asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
