The call

RainBytes and Cold & Breathwork both sit at 4.6 stars, but that hides the real split: 86% of RainBytes's written reviews are positive against 33% of Cold & Breathwork's. Cold & Breathwork's advantage is update cadence (every 5 days vs every 2 weeks) and iOS requirement (15.1 vs 18.0). On price, rating, ratings volume and ads there is nothing between them.
