Synca
Real-time shared timer — sync with anyone via a lin
Synca lets you create a countdown timer and share it with anyone via a single link. Everyone sees the same timer, in real-time — no signup required for guests. Perfect for remote meetings, online classes, study groups, poker games, escape rooms, or any situation where everyone needs to be on the same clock. Share a link → Everyone syncs instantly
Hi Product Hunt! I built Synca because I kept running into the same problem during remote meetings and online classes — everyone had their own timer running at slightly different times, and it caused constant confusion.
The idea is simple: one person creates a timer, shares a link, and everyone in the group sees the exact same countdown in real-time. No app install, no signup required for guests.
I've found it especially useful for:
- Time-boxed remote meetings (no more "how much time do we have left?")
- Classroom countdowns for exams or activities
- Study groups doing Pomodoro sessions together
- Poker blind timers shared across players
Would love to hear how you'd use it — and any feedback is very welcome!
