I really recommend the app Be My Eyes (google play/appstore), which connects blind & visually impaired users with sighted volunteers, for video calls related to small day-to-day tasks (choosing an item of clothing based on colour, checking expiry dates on food, etc). You are matched by language, and if a volunteer can't pick up a call from someone needing help, someone else will take care of it - calls go out to several volunteers at once. So yeah, great app, free, etc.
