Ancient Greek has two words for time. Χρόνος (chronos) is the clock — seconds ticking by, calendars filling up. But καιρός (kairos) is something different entirely: the appointed moment. The right time. A moment charged with meaning and purpose.
Every time you open Scripture, it's not just another minute in the day. It's a kairos — an opportunity to encounter the living God. This app exists to help you make the most of those moments.
"See then that ye walk circumspectly, not as fools, but as wise, redeeming the time — for the days are evil."
Ephesians 5:15–16 · “the time” = καιρός
