Random Timer Generator is a random countdown timer that allows you to input a Minimum and Maximum time, and then it will start a random timer somewhere within that range. Random Timer Generator allows you to create random timer countdowns, which makes it great as an exercise timer, a meditation timer, a random timer for studying, a Musical Chairs timer, or as a timer for Hot Potato style games like Catch Phrase, The Last Word, Pass The Bomb... or Hot Potato. ************************************ FEATURES * Fully configurable random countdowns with adjustable seconds, minutes, and hours * Supports timer durations from 0 seconds to 24 hours * The timer and alarm will still run properly even if your screen is locked or you have another app open * Enable or disable countdown noise options * Enable or disable vibrations when the timer ends * Enable or disable showing how much time is left while the random timer is going * Sounds an alarm when the timer hits 0. Choose from different alarm noise options, or go silent with vibrate-only option * Upload your own sound or song as the countdown sound, the sound when timer ends, or the sound when break period ends * Animates and vibrates when going off, so you'll notice the timer expiring in a noisy situation * Looping mode - set a random timer to go off repeatedly, so the next random timer starts again after one ends. You can even add a "break period between random timers", where you can set how many seconds you'd like as a break between random timers when Loop mode is on. * If Looping mode is on, it will tell you how many loops you have completed ************************************ Random Timer Generator is great for: * Games There are many Hot Potato style games where you don't want to be the person holding the ball (or potato) when the random timer goes off. Random Timer Generator works great for these Hot Potato style games, such as Catch Phrase, The Last Word, Pass The Bomb... or Hot Potato. Also great for board games where you need a random timer * Meditation When meditating, you may want to set a timer... but not know exactly when that timer will end (for example, a random timer that will go off somewhere between 10 and 30 minutes). Random Timer Generator works great for that. * Exercise While exercising, you may want to have a random timer for doing certain exercises, but not know exactly how long you will need to do it for. For example, you could set a minimum of 15 seconds and a maximum of 60 seconds while holding a forearm plank. * Musical Chairs With Random Timer Generator, you can set a random timer (for example between 5 seconds and 30 seconds) to go off for playing Musical Chairs. You can even have it playing songs while the timer is counting down. * Studying Andrew Huberman has popularized the Gap Effect or Spacing Effect method of studying, where you have a random timer go off every now and then while studying, to give yourself a short break. During that break, your brain replays what you were just learning at hyper speed.

ReceptionRating · Positive reviews · Number of ratings

RandLetter holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: Random Timer Generator has 56 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 80% of RandLetter's written reviews are positive against 83% of Random Timer Generator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

RandLetter ships an update every 16 months, Random Timer Generator every 2 months. The most recent releases landed on June 1, 2026 and September 12, 2026 respectively.
