Random Interval Timer App
A random interval timer app is for drills where you do not want a predictable countdown. Instead of fixed rounds, you get unpredictable cue moments and react instantly.
When random intervals are useful
- Martial arts: explode on the cue, then reset without anticipating the next one
- Footwork: burst, settle, burst again
- Conditioning: quick changes of pace inside a longer set
- Skill work: crisp reps at “go” moments (not on a metronome)
How Re:Do implements random cues
In Re:Do, random cues live inside an actual exercise (not a standalone beeper). Use Target mode to set a time window and a target number of cue moments. Then enable Random trigger sounds to play cue sounds at unpredictable times during the set.
Tutorial: build a “random cue” set
- Create an exercise in Target mode.
- Set duration (example: 3:00).
- Set Target reps (example: 12 cue moments).
- Enable Random trigger sounds.
- Add the exercise to a workout and run it in the Training Player.
Practical drill ideas
- “Burst + reset”: cue = 2–5 seconds hard work, then calm breathing until the next cue.
- “Defense first”: cue = slip/roll + counter combo (or sprawl + angle out).
- “Sprint start”: cue = 10–15m acceleration, walk back slowly.
- “Grip pop”: cue = one explosive pull/turn/stand-up rep with perfect mechanics.
FAQ
Is this the same as a HIIT interval timer?
Not exactly. HIIT timers are usually predictable rounds. Random cues are about reaction and execution quality.
Re:Do also supports normal interval structure when you want it.
Can I still plan full workouts?
Yes. Random-cue exercises can live inside a routine with warmups, main work, cooldown, and tracking.
Will this make my training “harder”?
It can. Start conservative, especially if you are doing explosive movements or striking.
