The clearest difference is ads: Pillow at none against Sleepzy's shown. Pillow also leads on update cadence (every 2 weeks vs monthly) and chart position (#149 vs unranked). Sleepzy's advantage is iOS requirement (13.0 vs 17.0). On price, rating, review sentiment and in-app purchases there is nothing between them.
