Senior Health Guardian – AI wins Rep. Vern Buchanan’s 2025 Congressional App Challenge in Florida’s 16th District

Rep. Vern Buchanan has named Gabriel Raymond Cacho, Omar Halwani, Amruta Velamuri, and Moksh Khemka of Lennard High School, Rouse High School, and Monta Vista High School as the winners of the 2025 Congressional App Challenge in Florida’s 16th District. Their app Senior Health Guardian – AI is an AI-based mobile and wearable application that monitors and looks out for elderly people through real-time fall detection capabilities, walking patterns for indications of Parkinson’s disease detection, and sleep and oxygen level monitoring for monitoring of cognitive health.

When asked what inspired the creation of Senior Health Guardian – AI, the students said, “The need for Senior Health Guardian arose out of our experience watching people that matter to us age and observed that existing technology is not designed to support that aging process with dignity and independence. We saw this in our families and circles, how seniors who wanted to remain active and independent were frustrated with balance and sleep issues, and how stressful it is for families that are concerned about their seniors but can’t be there all the time.

“We observed that all tools for seniors are basically passive. That is, they can provide assistance only after a negative event has occurred and are often triggered only when a button is pushed or a call is made. However, that is not always feasible in a situation like a fall. We wanted to develop a proactive system that has enough advanced AI capabilities to detect risks and immediately react to them without requiring seniors to press a button.

“During our research, we learned that small changes in walking patterns can foretell Parkinson’s many years earlier than a diagnosis and that a decline in sleep patterns can indicate a prelude to cognitive decay. Seeing this example, we realized that there is a huge opportunity that not only reacts to emergencies but can provide much earlier warning signs for preparation and better health for seniors.

“We were also keen to ensure that the technology felt positive and motivational rather than clinical and invasive. That’s why our designers developed gamification features that celebrate achievements and promote health and wellness. We think seniors can and should expect better than to have technology monitoring and judging them.

“In essence, we created Senior Health Guardian because we think that seniors shouldn’t have to give up their independence and their peace of mind when they age. We think that families need to feel more connected to each other. We think that seniors need to have more power over their lives. We think that technology needs to keep people protected even when a disaster isn’t occurring. We want to provide healthier and more independent lives for seniors through AI.”

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.
