Ski Sentinel wins Rep. Chris Stewart’s 2023 Congressional App Challenge in Utah’s Second District

Rep. Maloy has named Anda Xie, a 10th grader at West High School, as the winner of the 2023 Congressional App Challenge in Utah’s Second District.

When asked what inspired the creation of Ski Sentinel, the student said, “I was lucky to start skiing at a young age – 8, yet quite unlucky in my third experience on the slopes. Being utterly flabbergasted by the seemingly pattern-less expanse of blinding white and towering pines – not to mention a sudden snowstorm transpiring to erase my existence at the same time, I took a wrong turn and ended up on one of the most difficult trails in the entire ski resort. In the end, I had to be carried off the mountain like a teddy bear by ski patrol. Even after all these years, when I am exponentially better at skiing (and taking turns) my face turns a red akin to one of the stripes on our beautiful flag when I see a lost novice bumbling around on the mountain – taking me back to that dark, stormy night of my youth. 


This was not the last time uninformed skiing harmed my family. On another trip with my father on a foggy evening, I lost contact with him in the middle of a run. Only until minutes later did I realize that he had crashed into the stump of a tree, broke his leg and was unable to move. If I was not with him, he would have been unable to reach ski patrol and could have suffered far longer than the 4 months he spent in bed after this incident.

Unsafe and uninformed skiing not only is a danger to skiers – it also can damage the livelihoods of the community sustaining this sport. Skiers, uninformed on the location of amenities like restrooms end up ‘doing their business’ throughout the mountain, trickling down (for the lack of a better metaphor) this discharge into our drinking systems and into our homes. Pretty nasty – even for an unkempt teenage boy like me.

Uninformed skiing is unsafe and unhealthy for anyone unlucky enough to get caught in its tentacles. Besides, what is the point of skiing if you are so worried about getting lost or thumped with a tree trunk that it is not even fun anymore? Preserving this status quo is an affront to Utah’s spirit – a home of the greatest snow on earth. With this project, I proudly fulfill my citizen’s duty to protect Utah’s skiers, Utah’s mountainside community/economy and the sport of skiing – a salute to that lost 8-year-old stuck on the mountain.”



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.
