| Name | Circadian AI |
| Overview | Circadian AI describes a smartphone-based system that analyzes recorded heart sounds to support clinicians in identifying patterns that warrant further assessment. The provider presents it as a clinical workflow tool, rather than an unrestricted consumer diagnosis app. Its public app restricts sign-in to authorized hospital staff and clinical use and explicitly says it is not intended for personal use. This review did not establish an independent validation report or regulatory authorization for the earlier accuracy, patient-count and seven-second claims; those claims should not be treated as verified diagnostic performance. |

Previously suggested audiences, subject to clinical authorization rather than confirmed public availability:
|
| Pricing | No public price or verified consumer free plan was established from the reviewed official material. Contact the provider about clinical access and deployment terms. The earlier expected free or low-cost offer was speculative, not a confirmed price. |
| Tags | AI Health, Heart Disease Detection, Mobile Health, Acoustic AI, Cardiovascular Screening, Preventive Medicine, HealthTech, Smart Diagnosis |
| App Available? | An official web app is listed at app.circadian-ai.com with sign-in restricted to authorized hospital staff and clinical use. No account was accessed, recording uploaded or clinical test performed. A public iOS or Android store listing was not verified; this is not evidence that the company or service has closed. |
