Verdict
Dictionary.com and Acronym Finder both sit at 4.8 stars, but that hides the real split: 93% of Acronym Finder's written reviews are positive against 26% of Dictionary.com's. Dictionary.com's advantage is update cadence (every 3 weeks vs every 10 months) and ratings volume (328K vs 945). On price, rating, ads and in-app purchases there is nothing between them.
