Tech like this helps people in more subtle ways, too.

I bought an Apple Watch to monitor my heart rate because a symptom of something I was diagnosed with was it could cause it to speed up. When my doctor decided to take me off the meds that kept it lowered, it was only thanks to the data from my watch that she put me back on it - she didn’t believe me when I said my heart rate felt like it had started going too fast and I was running out of breath too easily after she took me off them (she pointed to blood test numbers as “proof” I didn’t need them anymore), then I pulled out my phone and pulled up the app that collated the data from my watch, and showed her the giant spike in numbers after she took me off the meds.

Then she went, “…ah,” and put me back on the heart meds. She wouldn’t have otherwise.
