From what I remember, Tinder allows you to set a preferred age range. If young folks set their preferred age to 65-80 and older folks set their preferred age range to 20-40, we can match people in need of groceries with volunteers.

Recipients and volunteers will just need to put a blurb in their bio about what they need or what they can deliver/provide.
