Verdict
The clearest difference is rating: S at 4.1 against EMA Manager's 3.1. S also leads on review sentiment (37% vs 16%) and ratings volume (89 vs 15). EMA Manager's advantage is update cadence (fortnightly vs monthly) and iOS requirement (13.1 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
