Be My Eyes is an app that connects vision impaired folks with volunteers to give them a brief spot of help.
It might be help with checking the colour of an item, or confirming that a light is on. That kind of thing.
Volunteers can just leave the app on in the background. By default they won’t receive requests during night hours but these hours can be edited to suit their preferences. If a request comes and it’s not a good time to take it, just decline or ignore it and will pass to the next volunteer.
There are about 20 times as many volunteers as there are blind users of the app, so the volunteers only get one request every month or so.
Consider signing up as a volunteer, and if you know any visually impaired folk, suggest this app to them.
