Verdict
FivePointFive and HYDROX both sit at 4.8 stars, but that hides the real split: 100% of HYDROX's written reviews are positive against 58% of FivePointFive's. FivePointFive's advantage is ratings volume (5.1K vs 4) and chart position (#85 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.
