Verdict
The clearest difference is review sentiment: WaterGuru at 74% against Minoston's 25%. WaterGuru also leads on update cadence (every 4 weeks vs every 9 months) and ratings volume (239 vs 66). Minoston's advantage is rating (4.5 vs 4.1) and iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
