Verdict
The clearest difference is monetization model: H2O at free against Water Tracker's freemium. H2O also leads on ratings volume (192 vs 32). Water Tracker's advantage is rating (4.8 vs 4.5) and review sentiment (100% vs 85%). On price, update cadence, ads and in-app purchases there is nothing between them.
