Verdict

The call

The clearest difference is rating: Terminology at 4.7 against Thesaurus's 1.0. Terminology also leads on ratings volume (1.1K vs 1) and update cadence (every 4 weeks vs every 2 months). Thesaurus's advantage is in-app purchases (none vs 2) and review sentiment (100% vs 71%). On price, ads and device support there is nothing between them.

Both are free to download. Terminology sells 2 in-app purchases, starting at $7.99 per year. Thesaurus asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Terminology holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Terminology has 1.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 71% of Terminology'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

Terminology ships an update every 4 weeks, Thesaurus every 2 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
