Verdict
The clearest difference is in-app purchases: Cloud Water at none against WhoseUp's 1. Cloud Water also leads on ratings volume (18 vs 3) and iOS requirement (12.0 vs 17.6). WhoseUp's advantage is review sentiment (100% vs 67%) and rating (5.0 vs 4.6). On price, ads and device support there is nothing between them.
