Rochester startup Casana replaces your toilet seat with a Wi-Fi wellness tracker that reads heart rate, HRV, SpO₂, respiration, blood-pressure insights, and sit-to-stand power every time you sit — no wearables, no cameras, no microphones. Limited launch at $199 for the seat plus a year of service; then about $10/month. Backed by General Catalyst, Kaiser Permanente, and Bemis. For wellness trends, not diagnosis. Source: casanacare.com
