Verdict
The clearest difference is ads: Rizzference at none against Acronym Finder's shown. Rizzference also leads on update cadence (every 3 months vs every 10 months) and rating (5.0 vs 4.8). Acronym Finder's advantage is ratings volume (919 vs 1) and device support (3 vs 1). On price, in-app purchases and monetization model there is nothing between them.
