MCZRandomTimer vs Randobeep

You can set the number of minutes, interval between showing a random number between 1 and 20, a Start and Stop button and you can set the random number to smaller or larger font.

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.
