Talking about apps for your phone…this one is amazing from MIT Media Labs.
Attach a $1-2 eyepiece (the "NETRA") to your phone and get your eye prescription in less than 2 minutes.
I wonder if they will come out with more apps for health and wellbeing that check your vital signs such as temperature, pulse, blood pressure, respiratory rate, and more.
I can envision the smartphone becoming our personal health assistant for monitoring and alerting us to dangerous medical conditions.
This will increase our ability to get timely medical care and save lives.
This is a long way from "I've fallen and I can't get up," and that's a great thing.
