BlockStatus wins Rep. Katherine Clark’s 2023 Congressional App Challenge in Massachusetts’s Fifth District

Rep. Clark has named Mori Finlayson-Johnecheck, an 11th grader at Arlington High School, as the winner of the 2023 Congressional App Challenge in Massachusetts’s Fifth District.

When asked what inspired the creation of BlockStatus, the student said, “There’s a lot to navigate in high school life these days. In a large public school like mine, there is a lot to manage every day: The class schedule changes daily, there are important announcements to keep track of, it’s unclear what time you have lunch, and coordinating with your friends can be a challenge. I wanted to create an app that would be helpful to students at my high school, and I saw an opportunity to do so with BlockStatus.

I realized that many students frequently wanted to check their schedules, the school announcements and figure out whether their classes were canceled, but it wasn’t convenient for them to do so. You had to hop through many websites with tiny font sizes that weren’t optimized for mobile devices. Most students went through the process anyway because this information was essential to the school day. The bell schedule changes daily, and the school loudspeaker system has problems, so only half the school can hear morning announcements.

I thought that if I created an app that was a quick all-in-one schedule & information center, people could save some time and be more informed. When I was working on early versions of the app, I didn’t realize the potential the idea had. In the spring, I was beta testing the app and many of my friends asked me what app I was using to see the schedule. I set up the app for them and later made it open to everyone in the school. Within the first week, 100 students signed up. Since then, I’ve added many more features based on user feedback, and over 1,200 people have used the app (80% of the students currently in the school). Having so many of my peers being able to benefit from my work continues to inspire me to make the app more accessible and useful.”

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.
