Casana's Smart Seat turns the most honest piece of furniture in the house into an Apple Watch for your backside — heart rate, oxygen, and "sit-to-stand power" every time you sit. No charging, nothing to remember, just $199 to start and the quiet knowledge that your toilet is plotting a trend chart. Guests optional; data shared only if you choose. Wellness, not a diagnosis — though the Toad reserves the right to laugh. https://casanacare.com/
