Verdict
The clearest difference is update cadence: SmartTub® at fortnightly against Sutro's every 8 months. SmartTub® also leads on rating (3.6 vs 3.2) and review sentiment (24% vs 0%). Sutro's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (12.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.
