# Terminology vs OneLook Thesaurus

The clearest difference is rating: Terminology at 4.7 against OneLook Thesaurus's 3.9. Terminology also leads on review sentiment (72% vs 33%) and ratings volume (1.1K vs 21). OneLook Thesaurus's advantage is device support (4 vs 2) and iOS requirement (15.0 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Terminology sells 2 in-app purchases, starting at $4.99 per year and OneLook Thesaurus sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Terminology holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: Terminology has 1.1K ratings behind it against 21, so its average is the more settled of the two. Written reviews point the same way: 72% of Terminology's written reviews are positive against 33% of OneLook Thesaurus's.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 24, 2026 and September 10, 2026 respectively.
