class25
Focused together, without the pressure of being watched.
class25 is a quiet online study room where users sit in a shared 3D classroom and focus for 25 minutes. I built it as a light, calm alternative to video-based study rooms.
Background
Studying alone can make it easy to lose focus, but video calls can feel too heavy for daily use. I wanted to create a quiet sense that other people are working in the same place, without conversation or camera pressure.
Approach
The app combines 25-minute focus sessions, 5-minute breaks, seat selection, presence, room statistics, and break-time chat. The classroom is shown from an angled 3D view so users can feel the space at a glance.
Result
I released a public web service with seating, leaving, presence, timers, and break chat. Through this project I learned how to design shared state for multiple users in a calm productivity product.
Enter the quiet online classroom.
