Verdict
The clearest difference is rating: Terminology at 4.7 against Wiktionary Reader's 3.9. Terminology also leads on review sentiment (71% vs 51%) and ratings volume (1.1K vs 63). Wiktionary Reader's advantage is in-app purchases (none vs 2) and iOS requirement (15.0 vs 18.0). On price, update cadence, ads and device support there is nothing between them.

Terminology ships an update every 4 weeks, Wiktionary Reader monthly. Both last shipped on November 1, 2026.
