Verdict
The clearest difference is ads: cpap.com at none against Knotty USA's shown. cpap.com also leads on rating (4.8 vs 4.4) and monetization model (ad-supported vs free with in-app purchases). Knotty USA's advantage is ratings volume (107 vs 34). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
