Chronos wins Rep. Abraham Hamadeh’s 2025 Congressional App Challenge in Arizona’s Eighth District
Rep. Abraham Hamadeh has named Vignesh Nagarajan of BASIS Phoenix as the winner of the 2025 Congressional App Challenge in Arizona’s Eighth District. Their app Chronos is a cross-platform scheduling intelligence tool that unifies calendars from different ecosystems, including Google Calendar, Outlook, and Apple Calendar, into one seamless interface.
When asked what inspired the creation of Chronos, Vignesh Nagarajan said, “Chronos was born out of frustration. The frustration of constantly trying to schedule meetings across fragmented digital ecosystems. As students and founders, our team lived between multiple calendars: our self-made school schedules on Google Classroom, internship calendars on Calendly, and personal reminders on Apple. The result? Occasional double-bookings, missed calls, and back-and-forth messages trying to find a single common time slot.
“The idea began when one of us tried to coordinate a three-person meeting between Google and Outlook users. What should’ve taken 30 seconds took several texts over three days. That moment sparked a realization: time coordination was broken, not because people lacked effort, but because their tools weren’t designed to communicate. We didn’t want another calendar app; we wanted a universal scheduling layer that could speak every calendar’s language. In essence, the idea to build Chronos branched from pain points that we experienced.
“Our inspiration grew from a shared belief that time is the most valuable asset people have, and wasting it on logistics is unacceptable. Chronos was created to give that time back. We envisioned a world where scheduling feels as simple as breathing.
“Beyond the personal frustration, we also noticed a growing professional need. As remote work, hybrid classes, and international collaboration became the norm, calendar fragmentation emerged as a universal problem. Teams spread across continents needed tools that understood their local contexts and time zones—not just static calendar blocks. Chronos’s AI-driven availability engine was built specifically to meet that need.
“The project evolved from a side project into a fully operational SaaS platform. Our early beta testers included student clubs, small teams, and independent freelancers. Their feedback confirmed what we suspected: people were tired of managing time; they wanted technology to handle it for them.
“We were inspired by the challenge of making time coordination invisible. The name ‘Chronos’ comes from the Greek word for time, symbolizing both control and flow. Our mission is to restore balance and to shift focus from scheduling meetings to actually doing the work. Ultimately, Chronos is something everyone can take advantage of. It reflects our generation’s reality: living across digital platforms, multitasking across worlds, and needing a single, intelligent system to bring it all together.”
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.
