Verdict
The clearest difference is rating: MIETHKE at 5.0 against HydroAssist's 4.1. MIETHKE also leads on review sentiment (100% vs 65%) and iOS requirement (11.0 vs 15.1). HydroAssist's advantage is ratings volume (27 vs 1) and update cadence (every 2 months vs every 5 months). On price, ads, in-app purchases and monetization model there is nothing between them.
