Verdict
The clearest difference is in-app purchases: Quantify at none against Emotly's 2. Quantify also leads on update cadence (daily vs every 2 months). Emotly's advantage is ratings volume (10 vs 2) and iOS requirement (13.0 vs 17.6). On price, rating, review sentiment and ads there is nothing between them.
