Verdict
The clearest difference is update cadence: 9D Breathwork at every 2 weeks against Marczell AI's every 4 months. 9D Breathwork also leads on ratings volume (255 vs 12). Marczell AI's advantage is review sentiment (100% vs 87%). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. 9D Breathwork sells 9 in-app purchases, starting at $67.00 per month and Marczell AI sells 6 in-app purchases, starting at $97.00 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for 9D Breathwork against 4.7 for Marczell AI. That said, the two scores are not equally well evidenced: 9D Breathwork has 255 ratings behind it against 12, so its average is the more settled of the two. Written reviews are what separate them: 87% of 9D Breathwork's written reviews are positive against 100% of Marczell AI's.
9D Breathwork ships an update every 2 weeks, Marczell AI every 4 months. Both last shipped on November 8, 2026.
