About this app

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 (works when screen is locked or other apps are active)

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 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, go silent with vibrate-only option, or upload your own sounds/songs

* 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

* If Looping mode is on, it will tell you how many loops you have completed

* Option to add a fixed break period between random timers (great for any who is studying using the Huberman gap effect, or great for having a rest period between workout sets)


************************************


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.

Very good!! I bought the pro version which makes this experience so much better, since I'm using it for teaching! However, there are some slight errors in the app, such as the sound when the timer ends would play a different tune than the tune that I selected, nevertheless, I usually just toggle it off and then back on again and then it works perfectly! :)

1. I'm using the loop function + 15 second break in between. Whenever the break ends it keeps on ringing over and over and doesn't stop even if I cancel it. So I have to force stop the app and start all over again. 2. The countdown doesn't show seconds, only minutes and seconds in the tens. So it appears like 5:1 (5 min 18 secs). I haven't used the app since last year and it seems the updates have made it even buggier.

Hey Krona, can you email me at daviswbaer@gmail.com with more info on what device you are using? Nobody else has reported this issue, so might be device specific

I'm writing the review again, because the developer misread the review before responding. This app has a bug in it. If I am watching youtube on my phone and the random timer goes off, the app interferes with youtube audio even after the app's sound stops. It makes other apps go down to half volume until the random timer app is exited and restarted. Please fix this bug. It appears the app is playing a silent sound after the buzzer goes off, rather than simply not playing sound anymore.

Hey J, that should not be the case. I will have my developer look into it.

What’s new

In the new update, you can now turn off vibrations when the timer ends.

Also fixed: Previously when you closed the app, it would not remember your sound choices. That has been fixed :)
