    Lonely old people now can buy “grandkids” by using an app named Papa. Through the app, elderly people can ask young people to come and visit them.

Elderly people, who may have lost touch with their own family, can also ask their rented(租用的) grandchildren to do chores and drive them around.

The elderly people can use Papa on the smartphone. If they don't have a smartphone, they can make a phone call. To use the service, the elderly people have to contact Papa first through either of the ways. The workers of Papa will provide advice for them for free and pair(配对) college students with them. Usually, the app costs the elderly people $15 an hour.

Most Papa Pals make about $20 to $30 per visit. The visit lasts around three hours. Andrew Parker, the founder of the service, says that Papa can also provide the service for people in need.
