I just learned about it today. It's an app that connects a sighted and a non-sighted person, showing the sighted person whatever is in the view of the non-sighted user's camera. I think it's a fantastic idea. It's used to see where someone dropped an earring, what the expiration date on the milk is, which sweater is the red one, or anything else you might need. Basically all the things I used to do for my buddy before he passed. I signed up today to help people in his memory. He was a huge giver, and made the world a better place. I want to keep that going for him by doing something I did for him. Right now there are seventeen times as many volunteers as users on the app. Eighty six thousand to one million four hundred eighty five thousand. I can provide links if anyone wants.
