Kairos vs Randobeep

Most timers tell you exactly when they end. Kairos does not. Set a minimum and maximum duration, start the timer, and Kairos chooses a random moment in between. You know the range. You do not know the exact finish. That simple twist makes Kairos useful anywhere timing should stay unpredictable.

Randobeep plays a beep at random intervals — never at the same moment twice. You set a minimum and a maximum in seconds. Every cue lands somewhere inside that range, which means you can't anticipate it. That unpredictability is the entire point. WHAT IT'S FOR - Reaction training — respond to a signal you can't see coming, whether you're drilling footwork, sparring, or working on sprint starts - Language practice — force yourself to produce a sentence on cue instead of rehearsing one in your head - Meditation and breathwork — return attention to the breath at irregular moments rather than settling into a rhythm - Focus checks — a nudge that asks whether you're still on task - Coaching and dog training — mark moments without falling into a predictable pattern HOW IT WORKS Drag the MIN and MAX sliders to set your range, anywhere from 1 to 60 seconds. Tap the orange button to start. The counter tracks how many cues you've heard. Tap again to stop. Set MIN and MAX close together for near-steady pacing. Spread them apart for genuine unpredictability. KEEPS GOING WITH THE SCREEN OFF Lock your phone or drop it in a pocket and the beeps keep coming.
