Chaos Clock is a unique iPhone app that offers timekeeping for Discordians. It allows users to measure both date and time according to the Principia Discordia and the Erisian Time Measurement system. From the first Sweetmorn in the season of Chaos to the last Setting Orange of The Aftermath, Chaos Clock provides a distinctive way to track time.

This app features a running countdown to X-Day, which is considered the end of the world by the Church of the SubGenius. Additionally, Chaos Clock includes St Tib's Day, the ten canonical Holydays, and 165 Holydays celebrated by various Discordian denominations such as Pi Approximation Day, Defenestration of Prague Day, St. John the Blasphemist's Day, Festivus, New Year's Eve Eve, and more.
