Verdict

The call

The clearest difference is ads: Terminology at none against Acronym Finder's shown. Terminology also leads on update cadence (every 4 weeks vs every 10 months). Acronym Finder's advantage is review sentiment (93% vs 71%) and iOS requirement (15.0 vs 18.0). On price, rating, ratings volume and in-app purchases there is nothing between them.
