Why is CountLink's free tier unlimited when competitors cap viewers?
Real-time competitors like ShareMyTimer and Stagetimer push live control changes (pause, extend, messages) to every open viewer instantly — that needs a server keeping a connection open per viewer, which costs money to run, so their free tiers cap devices and timers to control that cost. CountLink's sync works differently: the countdown's end time is written into the shared link itself, so every device just does its own local math against that timestamp. There's no ongoing connection and no per-viewer cost, which is the direct reason CountLink can offer unlimited viewers for free, indefinitely — showing the countdown to one person or ten thousand costs the exact same amount of nothing.
Common questions
- Yes, the shared timer is free with no viewer limit and no device limit — because syncing happens entirely in the link itself, not on a server, showing 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 encoded directly in the shared link as a timestamp — not stored on a server. When you press start, CountLink calculates the exact moment the countdown should hit zero and writes it into the URL you copy. Every device that opens that link reads the same timestamp and counts down to it using its own local clock, so there's no server round-trip, no polling, and nothing to fall out of sync.
- No — there is no server in the sync path at all, so there's nothing to go down. Each device is doing its own local math against the shared timestamp.
- Not pushed live to everyone who already has the link open — since there's no ongoing connection, there's no channel to broadcast a pause through. If plans change, the quickest fix is to start a fresh countdown and re-share the new link; for a fixed-duration class, exam, or webinar this rarely comes up.
- Sync accuracy depends on each device's own clock being roughly correct, typically within a second — the same margin any phone or laptop clock holds day to day. The countdown itself doesn't drift; any tiny difference you'd see between two screens comes from the devices' clocks, not from CountLink.
