GlucoScan wins Rep. Deborah K. Ross’ 2022 Congressional App Challenge in North Carolina’s Second District

Rep. Deborah K. Ross has named George Cheng of North Carolina School of Science and Mathematics and Sameer Khan of Green Level High School as the winners of the 2022 Congressional App Challenge in North Carolina’s Second District.

When asked what inspired the creation of GlucoScan, the students said, ”My mother developed gestational diabetes which later transposed into Type-2 Diabetes when I was born; it was always a burden since I was the cause of her diagnosis. When I was given a chance to explore computer science, I knew the first thing I wanted to create was a device that can reduce my mother’s use of the pricking mechanisms (needle-intrusive methods). Therefore, I found a noninvasive salivary glucose method through programming and using the smartphone’s Bluetooth capabilities to detect salivary glucose levels. As my sister developed Type-2 Diabetes as well (from a familial history of Type-2 Diabetes and Prediabetes), I knew that launching the GlucoScan App was the only way we can monitor and actively track her glucose levels.

Secondly, I also want to solve the diabetes prevalence in North Carolina. Along with the nonprofit organization I created (, I want to help through actual medical means as well; the motivation to use GlucoScan in low-income communities will hopefully lower the progression of Type-2 Diabetes or overweightedness to prevent a continuous onset of this disease. Many friends and families of mine each year die from a lack of support from medical care providers or simply neglect their bodies because of how complicated complex glucometers can be, GlucoScan aims to remove this stigma and ease users into using GlucoScan for better access to detection services.”

The Congressional App Challenge smashed previous participation records in 2022. All told, 9,011 students registered for this year’s competition – creating 2,707 fully-functioning apps for 335 Members of Congress across 50 states, Puerto Rico, Guam, the Mariana Islands, American Samoa, and the District of Columbia. This year’s competition set the record for most student registrations, most apps submitted, most apps per district submitted, and most districts receiving over 20 apps. The wildly successful competition continues to impress upon House Members the importance of computer science education and the need to develop a pipeline of diverse, domestic STEM talent. 

The Congressional App Challenge is an official initiative of the U.S. House of Representatives, where Members of Congress host contests in their districts for middle school and high school students, encouraging them to learn to code and inspiring them to pursue careers in computer science. Each participating Member of Congress selects a winning app from their district, and each winning team is invited to showcase their winning app to Congress during our annual #HouseOfCode festival. The program is a public-private partnership made possible through funding from Omidyar Network, AWS, Rise, theCoderSchool, Apple, and others.

The 2023 Congressional App Challenge will launch in June of 2023, and eligible students can pre-register for the competition now.
