Lunchroom App Work for Elders?

I was reading an article in the Washington Post about a young woman who was bullied at school. Drawing on her experiences, she created an app for kids who don’t have anyone to sit with at lunch.  This once-bullied teen has a simple solution so no one has to eat alone in the cafeteria ever again describes this app and her motivation in creating it.

[She] came up with an idea that would allow students a judgment-free way to find lunch mates without the fear of being rejected. She developed an app called “Sit With Us,” where students can sign up as “ambassadors” and post that there are open seats at their lunch table. A student who doesn’t have a place to sit can look at the app and find an ambassador’s table and know they are invited to join it. When signing up as an ambassador, the student takes a pledge that they’ll be kind and welcoming to whoever comes to sit with them.

Kudos to this inventor!

Although we may think of bullying as a problem faced primarily by children and young adults, happening in schools or in cyberspace. Of course, that is not the case.  Elders can be bullies as well.   So I was thinking-this app could have use beyond lunch at a school cafeteria.  What about its use for an event at a senior center, independent living facility, CCRC, ALF or SNF.  It seems it could be incredibly useful in providing a boost to socialization.  I realize not every elder is tethered to her smart phone, but that surely may change over time.  So, what do you think?  Would this be helpful? Is this already being done?
