Verdict
The clearest difference is rating: Numerical³ at 4.8 against WaterCo's 1.0. Numerical³ also leads on ratings volume (1.3K vs 2) and update cadence (every 2 weeks vs monthly). WaterCo's advantage is monetization model (free vs paid) and iOS requirement (7.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
