Randobeep

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. Built for sessions where you're moving, not watching a screen.

NO ACCOUNT, NO INTERNET, NO DATA

Randobeep runs entirely offline. No sign-up, no tracking, no analytics, no ads. Nothing you do in the app ever leaves your phone.
