That’s a killer combo—smart tech + home care. Start with a lightweight sensor kit that tracks vitals, movement, and sleep patterns, then feed the data into a simple app that gives instant alerts when anything deviates from the user’s baseline. Keep the interface minimal: one screen with a big, clear “All good” icon that turns red or yellow if something’s off. To stay safe, make every alert automatic and double‑check with a quick voice prompt or text. For privacy, encrypt all data on the device and only sync to the cloud with the user’s explicit permission—no sharing unless they opt‑in. Finally, let the system learn routines by observing patterns over a couple of weeks, but give the user a “teach” button to override or tweak the model when the AI misreads something. That way it feels personal but not invasive. How does that sound?
