Verdict
The clearest difference is rating: Whisker at 4.8 against Ember's 3.3. Whisker also leads on review sentiment (52% vs 18%) and ratings volume (147K vs 7.4K). Ember's advantage is monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and iOS requirement there is nothing between them.
