Testimonial “It works” says Larisa_M on App Store, on Oct 15, 2017:

I’ve always taken an hour or so to fall asleep. This made my life hell when my baby woke up once an hour. Even then, with extreme sleep deprivation, it still took me an hour to fall asleep. With this app, I fall asleep in 10 minutes. It’s amazing how well it works. It’s like it flips the “off” switch in my brain.

Testimonial: "this shuffle business does exactly what it says" (Penny in UK)

What an excellent app this is. I have come to rely on it, for sure. After years of using music, which has mixed success, this shuffle business does exactly what it says on the tin.

Sometimes it fails to engage me and now I know that I must breathe and release my inner thoughts and let the sleep app take dominance.

The app works, like magic. Anytime I have trouble with my mind keeping me awake, this app is the cure. Support is great; I reported an issue on a version of Android and they were friendly and helpful. Now fixed! The cost is trivial for the incredible value it offers. Highly recommended.


App works great. I fell asleep way faster than I would normally and was far more productive the day after. 10/10 would recommend.


This app was recommended to me by my doctor. I was somewhat skeptical but decided to give it a try and was pleasantly surprised that it actually works to put me to sleep. Great app.


This app is awesome. It really helps me go to sleep quickly. The latest update works well on my Galaxy3.

Testimonial: "I downloaded your app and our lives changed for the better!"

No method for falling asleep, including serial diverse imagining, works for everyone. There's always more R&D to do on this subject, and we keep on doing it. Stay tuned for some major, exciting developments about our R&D, including mySleepButton, in Dec and in 2018!

We receive a lot of positive feedback about mySleepButton, and are very pleased about our ongoing research programme. We received the following testimonial recently from Scott S of BC (Canada).

I'm emailing to say thank you.

My son is three years old. He's had problems falling asleep. Some nights he was up late and was grumpy the next day. In fact I'd be grumpy too because my night consisted of tucking him and snuggling him over and over for hours.

Then I downloaded your app and our lives changed for the better!

We've been using My Sleep Button for months as part of our bedtime routine for him. He even asks for “visualization” each night as the last thing we do together.

I personally enjoy a little nap with him at bedtime as I too fall asleep to the sound of “visualization”.

Thank you for not only helping our son fall asleep but also for helping our family have a positive bedtime routine.

If you ever choose to make swag, t shirts or PJs etc, please let me know. It would be so cool to put on our My Sleep Button clothes before bed with our son.

We started using the app in early 2017. It's nearly been a year.

We've been using the Simple Things pack but recently downloaded the kids' pack and have been using that.

Keep up the great work!
You've made a huge difference in our family!

Scott S from B.C.

For more information about the children's pack, please see Kids Pack: The Cognitive Shuffle and Children's Sleep. Notice that this parent was with the child. Some parents liken this to reading a bedtime story. It is also possible to broadcast mySleepButton to a wireless speaker, which ensures that the mobile device (smartphone or tablet) is not in the same bedroom as the person trying to fall asleep, sleep guidelines discourage leaving mobile devices with children at bedtime.

Recognition at FRSAC2017

At the 3rd annual First Responders Suicide Awareness conference, Dr. Patrick Baillie recommended mySleepButton as a useful tool.  As noted by Cst. Jeremy Shaw, sleep disorders among first responders are a big issue.

We are truly grateful that we can help so many, including first responders, with their sleep struggles.

Oliver Burkeman, The Guardian 2017-09-08

My top recommendation remains the visualisation method known as the “cognitive shuffle”: download the MySleepButton app, or just choose a letter of the alphabet and sequentially imagine objects beginning with that letter.

"No More Drugs": Anonymous Female Testimonial

I am 71 and have been unable to easily fall sleep without lorazepam for years. When I started reading about the possible harm the drug might be doing, I went into action. I read about sleep and tried a number of apps. Then I came across an article in Forbes. Then I read more about your app and the cognitive shuffle. I was intrigued. It made perfect sense.

I tried the app a week ago and I fell asleep. The next night I put it on for an hour so I would not end up worrying that it would end before I fell asleep. I have fallen asleep every night, sometimes in minutes, but never more than around 20 minutes. No more drugs.

Thank you.

Heard about this on and it works! If you have trouble falling asleep.... (Tweet)

I went into this technique with total disbelief, entirely skeptical. And it worked on me like a charm. It has been effective every night since. I love it because it’s drug-free and I can even do it with a cat sleeping on my hand. If you have trouble falling asleep I can’t guarantee it will work, but there is literally no harm in trying it.

Marj "OMG – I was astonished. It worked" (May 1, 2017 testimonial)

All I can say is …. this is the answer to sleepless nights, when the hamster wheel is in overdrive. I feel like I haven’t slept for months, having a really tough time, waking up in the morning feeling exhausted. I heard a quick snip on CBC radio re: Serial Diverse Imaging, interest piqued for obvious reasons ! I down loaded the App last night, OMG – I was astonished. It worked, even though I woke up three times, each time putting mySleepButton back on, I fell right back to sleep. I want to say THANK you Dr.Beaudoin, and all the other scientists involved in coming up with this brilliant App.

Anonymous Testimonial

Thanks guys. It has really helped me get to sleep at night!

Travelling Guardian Reader, S.B. (Testimonial)

i first became aware of your technique from the guardian. i travel a lot and find it difficult some times to fall asleep. new city, new clients , old clients complaining etc etc. My biggest problem was getting to sleep early and then waking after a couple of hours of rest and not being able to get back to sleep.

so i tried a very uncomplicated version as explained in the Guardian article. i am amazed [at] its effectiveness. I have been using the technique (just choose a letter and think and visualise the object 3 to 4 seconds) repeat until asleep. now i barely get past the 3rd or 4th word. it as if the brain has said " ahhh he is doing that thing again put him to sleep.)


Brett Terpstra, Read and Trust Productivity Blogger, Podcaster, App Developer

The act of changing completely what you’re thinking about every 15 seconds or so disrupts your brain from being able to get onto what you were thinking about, to get onto those racing thoughts that keep you awake at night…

You just start to drift off and fall asleep.

I’ve found [mySleepButton] very effective to get into that really drowsy state where no thoughts can penetrate anymore.

This works better than Pzizz for me.

Trouble sleeping? The free, http://mysleepbutton.com app from @CogSciApps will knock you out without drugs. I tried it, and it really works.

James Harcus (Port Coquitlam Firefighter)

I've been using the cognitive shuffle for over a year now. Every time I can't get to sleep because I have had too much coffee or whatever, I just do the cognitive shuffle and it knocks me into sleep.

Mike King (BC)

I'm a father of 5 kids and work full time. After a full day working I take the kids to baseball, volleyball and dance classes and usually don't get home until 9pm. On May 12th, I was reading about the mySleepButton app and I decided to give it a try instead of trying to fall asleep watching TV, which would normally take about an hour. I was fast asleep within 15 minutes. The next day I was asleep in 10 minutes. Make sure you tell your other half what you're doing. She walked into the room and couldn't figure out how to turn off the sleep app and woke me up!!

"Heard the interview, downloaded the app and slept like a baby last night. :). This is awesome!"

Dr. B. (British Columbia)

A testimonial about mySleepButton:

I downloaded the app onto my phone yesterday when I got home from work and started playing around with it. Hit the "Put Me to Sleep" button and started to listen. I was a bit unimpressed - seemed a bit dull - not as relaxing as guided meditation imagery - voice didn't grab me …….. Then I woke up 30 minutes later, sitting on the couch with a terrible crick in my neck!!!
So it definitely works for me!

Used it again at bedtime (lying down this time!) although I normally do go to sleep easily, but more impressively I used it again in the middle of the night and it worked like a charm. I'm not sure how I will save the world's problems without my habitual 3AM ruminating, but I am a total convert to this app!
[…] this is terrific.

Serge Beaudoin (Director General, Aboriginal Affairs and Northern Development Canada)

I sometimes wake up at night and think of work and other issues and that can keep me awake for long periods. My brother's technique (the cognitive shuffle) helps me fall back to sleep quickly and it has been extremely effective for me -- in fact, almost as effective as speaking to him directly.

R.M. (British Columbia)

I used the technique about 15 times and found it to be effective every time.

Nicki P. (California)

Nearly every night I use this technique. When I am ready to go to sleep (I am in bed with the lights out) I think of a word and then start with the first letter of the word and see how many words I can make and imagine with that first letter.  Then I go to the next letter and do the same thing. It is not very often that I have to go to a second word - this really does work to put me to sleep.

Michael Arsenault, MD (Pediatric Emergency Doctor, St-Justine Hospital, Montréal, Québec)

This technique has allowed me to stabilize my sleep cycle which is constantly disturbed by shift work in the ER. It really has helped me recuperate and function under high stress.

Judy Garner (California)

I have been falling asleep much faster since I started using the random word imaging method that Luc taught me. It words much better than counting backwards which I used to do. I also use it to "drop off" for an afternoon nap occasionally.

Jean (Quebec)

Finally a sleep aid that works and all without side effects. I use it often.
