A new app created by a 16-year-old California girl aims to make sure no child eats his or her school lunch alone.

Natalie Hampton developed the idea for the Sit With Us app, which launched Sept. 9, to help students find kindness and welcoming groups with whom to eat in school lunchrooms across the country.

"Lunch might seem really small, but I think these are the small steps that make a school more inclusive," Hampton told the Washington Post. "It doesn't seem like you're asking that much, but once you get people in the mindset, it starts to change the way students think about each other. It makes a huge difference in how they treat each other."

The now-high school junior told the Los Angeles Daily News that she was inspired to create the app after she ate lunch alone for her entire seventh-grade school year. She said the experience made her feel lonely and vulnerable and made her a target for bullying, which lasted into her eight-grade year.

Hampton told the Daily News that she suffered from nightmares, stress and depression as a result of the bullying, and at one point, she was hospitalized for health issues.

"I was a shell of the person I was. When I walked into a classroom, I was planning an escape route," Hampton said.

The app allows students to connect with other students at their schools, chat with other users to coordinate a lunch, post featured lunches for others to join and search for lunches nearby.

Users create a profile, add friends and describe their interests. Users have the option to designate themselves as "ambassadors" who create "open lunch" events and invite others to join them. The open lunch events serve as go-aheads for all interested students to join the ambassadors' table.

"Sit With Us was born because I am committed to making sure that other kids don't suffer as I did. I believe that seemingly small, incremental changes in the overall dynamic of a school community can bring about change, so that everyone feels welcome and included, " Hampton wrote on the app's official website. "I believe that every school has upstanders like me, who are happy and willing to invite anyone to join the lunch table. It is my hope, with people pledging to be ambassadors at their schools, that no one will feel left out."

Hampton said the new app is especially helpful because the electronic process prevents children from being publicly rejected and being considered social outcasts by their peers.

"This way it's very private. It's through the phone. No one else has to know," Hampton told Audie Cornish on NPR's "All Things Considered." "And you know that you're not going to be rejected once you get to the table."

The Sit With Us app is free and recommended for children of middle school age and older.
