The Hot Potato Timer
Set a range, press Start, and pass the phone (or the actual potato): the random timer generator picks a secret moment somewhere in your range and rings without warning. The countdown is never shown while it runs — the pulsing orb is the only thing anyone gets to watch, so there are no tells and no counting along. Whoever's holding it when it shrieks... loses.
Random Interval Timer
Turn on repeat mode and this becomes a random interval timer: after each ring it pauses a couple of seconds, then starts a fresh round with a brand-new random duration, indefinitely. Each interval is drawn independently from your range, so the gaps never fall into a rhythm — useful for exactly the situations where predictability ruins the point:
- Reaction training — sprint starts, boxing slips, goalkeeper dives on an unpredictable cue
- Posture and focus checks — a nudge at irregular intervals is harder to tune out than a fixed one
- Dog and horse training — variable-interval reinforcement, straight from the behavioral textbooks
- Party game rounds — hands-free hot potato, round after round
If you want fixed repeating intervals instead — every 5 minutes exactly — use the repeat timer.
Games and Uses
- Hot potato / pass the parcel — the classics; use repeat mode for round after round
- Classroom attention — "when the timer rings, whoever is talking answers the next question"
- Musical statues — freeze when it rings
- Workout surprises — hold the plank until the random ring; pairs with the HIIT timer for finishers
- Random checks — posture, hydration, "are you actually working?" moments
FAQ
Is every moment in the range equally likely?
Yes — the ring time is drawn uniformly between your minimum and maximum, so it's just as likely to ring early as late. The suspense is real.
Can I see how long it's been running?
If you want — turn on "Show elapsed time". It shows time since the start, never time remaining, so the surprise survives.
What's repeat mode?
After each ring the timer pauses for a couple of seconds, then starts a fresh round with a brand-new random duration — hands-free rounds for party games.
