Watts® Home and NEX Smart both sit at 4.6 stars, but that hides the real split: 100% of NEX Smart's written reviews are positive against 28% of Watts® Home's. NEX Smart also leads on update cadence (every 2 weeks vs every 3 months). Watts® Home's advantage is ratings volume (4.2K vs 4) and iOS requirement (12.2 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.
