Other people have already responded, but I wanted to add my two cents because I use mine as a disability support. It was paid for out of my National Disability Insurance Scheme plan here in Australia, and they’re known for being tough about the things they will cover.

• Calling or texting formal & informal supports to ask for help when without my phone or it dies.
• Medication reminders I can’t miss.
• Metrics like: Walking Speed, Step Length, Asymmetry, Steadiness and Double Support Time that help my Physio and OT with assessment and therapy. Important because I use a cane or walking frame 95% of the time.
• Detailed heart data that helped me have my POTS diagnosed. Heart meds have helped me be able to exercise way more without tachycardia.
• Paying without needing to juggle things with one hand (using cane in other hand).
• Smart home control for things like lights, blinds/curtains, fans, aircon, heating, TVs, computers always on my wrist.
• Sleep & Exercise tracking help me feel validated when my body hurts more than usual.
