Verdict
Sub and Watts® Home both sit at 4.4 stars, but that hides the real split: 28% of Watts® Home's written reviews are positive against 15% of Sub's. Watts® Home also leads on monetization model (free vs ad-supported) and ratings volume (4.1K vs 786). Sub's advantage is update cadence (every 5 weeks vs every 3 months). On price, rating, ads and in-app purchases there is nothing between them.
