The clearest difference is review sentiment: Antibiotic at 100% against MobilEM's 45%. Antibiotic also leads on rating (5.0 vs 3.6) and in-app purchases (none vs 12). MobilEM's advantage is ratings volume (39 vs 4) and chart position (#43 vs unranked). On price, ads, device support and iOS requirement there is nothing between them.
