    If you see a problem, you should find a solution. That is what Alex Knoll, a 13-year-old boy from Post Falls, Idaho, believes. When he noticed a man struggling to open a heavy door from his wheelchair, Alex started thinking. "I wondered if there was a resource available to him to show which business had automatic doors, so he could actually access them, "Alex told Time for Kids."I couldn't find anything, so I created it."

That was four years ago. The idea is Ability App. Alex's website says the app will help people with disabilities and their caregivers find the exact position of public spaces and find safe, reliable services and employment opportunities. Talk-show host Ellen DeGeneres liked Alex's idea so much that she had him on her show and surprised him with a $25,000 check. "I think it's really going to help me get going, " Alex says.

Worldwide, there are more than a billion people with some kind of disability, according to The World Health Organization. A disability can make it hard to do everyday activities and find a Job. Tara Miller is a friend of Alex's family. She uses a wheelchair. She helps Alex with his app by sharing her experience of what it is like to live with a disability. "We all want to be able to be in the same establishments(机构) as any able-bodied person, " Miller says. "It' s about little things like low tables in restaurants and automatic doors, which can make a huge difference, she says. Alex has yet to set a launch (发布) date for Ability App. But he is determined to meet his goal. "I'm going to work as hard as I can and as fast as I can, "he says.
