Shared timer, synced by link
One timer. Every screen. In sync.

Quick timer, or count down to a moment on the clock — both produce a shareable link.
Why doesn't CountLink limit viewers like competitors do?
Real-time competitors like ShareMyTimer and Stagetimer push live control changes to every open viewer, which needs a server holding a connection open per viewer — that cost is why their free tiers cap devices and timers. CountLink works differently: the countdown's end time is written into the link itself, so each device just checks its own clock against that timestamp. No ongoing connection, no per-viewer cost, no reason to cap viewers.
Common questions
- Yes — no viewer limit, no device limit, no paid tier. Syncing happens in the link itself, so one more viewer costs nothing.
- No. Nobody — neither the person who starts the timer nor anyone who opens the shared link — ever needs an account.
- The countdown's end time is a timestamp written into the shared link, not stored on a server. Every device that opens the link counts down to that same timestamp using its own clock.
- No — there's no server in the sync path, so there's nothing to go down. Each device does its own local math against the shared timestamp.
- Not live, for everyone already viewing — there's no ongoing connection to push a change through. If plans change, start a fresh countdown and re-share the new link.
- Accuracy depends on each device's own clock, typically within a second. The countdown itself doesn't drift — any difference you see comes from the devices' clocks, not from CountLink.
