BE PRESENT Live project: https://b-prsnt.vercel.app/ We've all been there. You're at dinner with friends and somehow, without deciding to, everyone's on their phone. The conversation just... stops.

I wanted to build something that actually changes that — not by lecturing anyone, but by making it a game. What if the person who checks their phone the most has to buy dinner? The idea: B.prsnt tracks phone usage during social gatherings, automatically, through the browser. The host sets the stakes, everyone joins with a code, and the app does the rest. Every time someone leaves the window, their time goes up. No manual logging, no honor system. When the session ends, the ranking is revealed and the loser faces whatever the group decided at the start.

No app to install. Runs in any mobile browser. Takes 30 seconds to set up. How I built it: It started with research — brainstorming the problem space, defining the project, and refusing to open Figma until the problem was validated. I built and deployed a survey from scratch (React, Supabase, Vercel) and ran it live during the makeathon. Real responses from real people confirmed this wasn't just something I felt personally.

From there: project definition, first sketches, a prototype focused on getting the core timer mechanic right. Then a full design and iterate phase — flow redefinition, game ideas, more sketches. Final hours were iterate, fix, and ship ASAP.
