About the game

Time without a clock face.

Syncd is a precision timing game by XOXO Software. It asks you to trust your sense of a second rather than follow a visible countdown.

Why an invisible timer?

Counting time feels easy until the feedback is measured in milliseconds. Syncd makes that gap between instinct and measurement the whole challenge. Press and hold to begin, release on a target between one and five seconds, and see your error immediately. The next round asks you to use what you learned.

The colored rings, moving marker, and result labels give each attempt a clear start and finish. They do not replace the central challenge: deciding when to let go. There is no required Syncd account and no elaborate setup between you and a run.

Built for short sessions

One release can take just a few seconds. Successful rounds collect points; a miss ends the run, so you can retry and refine your rhythm. The best score and best completed round are stored on the device you play on. Mobile versions may offer platform services such as Apple Game Center; availability can differ from the browser version.
