As someone who’s never been a huge fan of React, I found myself diving headfirst into building TimeMomo - a real-time collaborative timer platform. This project was born out of a desire to learn more about modern web development stacks while creating something genuinely useful.
TimeMomo is designed for presenters, streamers, and event managers who need to share timers with audiences in real-time, without the complexity of traditional WebSocket implementations.
What is TimeMomo?
TimeMomo is a collaborative timer application that allows users to create “rooms” where timers can be started, paused, and synchronized across all participants in real-time. Think of it as a professional timer platform for:
- Presenters who need to manage speaking time during conferences
- Streamers who want to share countdowns with their audience
- Event managers coordinating multiple sessions
- Meeting facilitators keeping discussions on track
Features
- Real-time Sync: Timer updates propagate instantly to all room participants
- Room Management: Create private or public timer rooms
- Multiple Timers: Run multiple timers simultaneously in one room
- User Authentication: Secure room ownership and management
- Responsive Design: Works seamlessly on desktop and mobile
- Clean Interface: Minimal, distraction-free timer display
Technical Details
- Built with: React, Next.js 15, PocketBase, TypeScript, Shadcn/UI
- Real-time: PocketBase real-time subscriptions
- Platform: Web (all modern browsers)
- Hosting: Vercel + Supabase
- License: MIT

Using TimeMomo is simple - create a room, share the link, and everyone sees the same timer in real-time.
