ClockIn! wins Rep. John Larson’s 2023 Congressional App Challenge in Connecticut’s First District

Rep. Larson has named Ryan Duong, a 12th grader at South Windsor High School, as the winner of the 2023 Congressional App Challenge in Connecticut’s First District.

When asked what inspired the creation of ClockIn!, the student said, “As a teenager, I’ll admit it: I struggle to keep on top of things. Whether it’s work, school, family responsibilities, clubs, or whatever else life can throw, it gets hard to keep track of where I’m supposed to be, and what I’m supposed to do.

As a teenager, I’m a serial procrastinator: last-minute deadlines, pushing things off until the last possible moments, you name it. On one hand, I hate the idea of pushing it last-minute, but on the other, I just can’t seem to break that tendency in my head, regardless of whatever strategy or trick I find on the Internet.

With that in mind, I wanted to program not just any other app, but an app that I know I could use for myself, and see the tangible benefits with my own eyes. That way, I’d know whenever I was developing the interface, or programming the app, or testing it out for myself, that I could figure out whether or not ClockIn! would be effective (the answer to which is a resounding yes). But it’s not just all about me. My issues with procrastination and time-management aren’t unique to me. I’m one of many from all across the district, the state, and the world that have fallen into the trap of these unfortunate tendencies. With ClockIn! I feel like I’ll be able to do my part, even if it’s minor, in helping to provide a remedy to those all around me. In fact, it’s my current goal to work on getting this published onto the Google Play Store.

I also wanted to pay a bit of homage to my Android-loving parents as well, so I decided on programming this as the mobile Android application that it is.And with that, there’s the origin story of ClockIn!”

This year’s Challenge saw an unprecedented level of participation, with 374 Members of the House of Representatives hosting competitions, surpassing the previous record of 340. A remarkable 11,334 students from across the United States competed in this year’s Challenge, marking an impressive increase of nearly 1,000 participants compared to the previous record set in 2019. The enthusiasm and creativity these students display is a testament to the growing interest in technology and signal a bright future for American innovation. The surge of ingenuity continued with a whopping 3,645 original applications flooding in, nearly a thousand more than the previous year’s high. This remarkable growth showcases the exceptional talent and innovation within our nation’s youth.


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. This resounding show of bipartisan support emphasizes the critical importance of STEM education in today’s rapidly evolving world. 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 2024 Congressional App Challenge will launch in May of 2024, and eligible students can pre-register for the competition now.
