Flexeon wins Rep. Steven Horsford’s 2025 Congressional App Challenge in Nevada’s Fourth District

Rep. Steven Horsford has named Daniel Chang, Elijah Ladot, and Xuanzhe Wang of Ed W. Clark High School and Advanced Technologies Academy as the winners of the 2025 Congressional App Challenge in Nevada’s Fourth District. Their app Flexeon is an AI-powered home physical therapy app designed to help older adults and uninsured patients recover independently and safely when they may not have access to traditional physical therapy.

When asked what inspired the creation of Flexeon, the students said, “This past summer, one of our team members’ grandma fell and broke her wrist. The doctor prescribed her physical therapy twice a week for six weeks in hopes of helping her wrist recover. However, long commutes and limited mobility contributed to her missing many of these appointments. Our team member saw that at home, she tried to perform these exercises alone, but most of the time, the exercises were done incorrectly.

“Watching her struggle, our eyes were opened. We realized that physical therapy needed to be made accessible to everyone who needed it. Through research, we learned that one in every two adults needs some sort of physical therapy. To make matters worse, most insurance plans only cover 20-60 sessions of physical therapy a year. This leaves a majority of people, especially the elderly and uninsured, on their own.

“Therefore, we searched for alternatives that these patients could use at home. To our surprise, there was a noticeable gap in the market for an app that could provide live physical therapy feedback at home.

“All three of us, wanting to apply our knowledge and technological skills from prior Congressional App Challenges and other competitions, decided to work together to address this issue. We also wanted to test out innovative libraries and models such as MoveNet and TensorFlow Lite. This contributed to us uniting on this project.

“By witnessing firsthand the serious gap in our community regarding physical therapy accessibility, we were inspired to conceptualize an app that could provide live physical therapy feedback at home, which became Flexeon.”

The 2025 Congressional App Challenge marked another record-setting year for the program. A total of 394 Members of the U.S. House of Representatives hosted App Challenges in their congressional districts, the highest level of participation in the program’s history. More than 13,800 students from across the country participated, submitting over 4,600 original apps focused on real-world challenges ranging from health and accessibility to education, sustainability, and civic engagement.

The Congressional App Challenge is an official initiative of the U.S. House of Representatives that encourages middle school and high school students to learn to code, explore computer science, and build practical technology solutions for their communities. Each participating Member of Congress selects a winning app from their district, and winning teams are invited to showcase their projects to Members of Congress, staff, and industry leaders at the annual #HouseOfCode celebration on Capitol Hill.

The Challenge is proudly bipartisan and reflects a shared commitment to expanding access to STEM education and preparing the next generation of American innovators for the future workforce. The program is a public-private partnership made possible through funding from the Broadcom Foundation, AWS, Infosys Foundation USA, theCoderSchool, Apple, and others.

The 2026 Congressional App Challenge will launch in May, and eligible students can pre-register for the competition now.
