Verdict
The clearest difference is monetization model: Simple Hydration Tracker at free with in-app purchases against Hydro Coach's subscription. Simple Hydration Tracker also leads on review sentiment (100% vs 64%) and rating (5.0 vs 4.7). Hydro Coach's advantage is ads (none vs shown) and ratings volume (950 vs 1). On price, update cadence, in-app purchases and device support there is nothing between them.
