Prof. Colin Espie (University of Oxford), world sleep expert and creator of Sleepio says "The most effective, long-term solution for poor sleep is a cognitive and behavioral approach, which addresses the mental and behavioral parts of the individual's sleep pattern. These approaches help the person to think and behave differently in relation to their sleep, which encourages good sleep to return. Sleepio is a clinically proven digital sleep improvement program that uses cognitive and behavioral techniques to help users with persistent sleep problems."

Mixed feelings-probably helpful if you don’t have kids

At first I really liked this, but now the prof is too long. I really wish it had subtitles.

I think this app is designed for a one size fits all person. I have young kids. This means I will wake up at night. There is no variation for this type of situation. As a result, the app and the lessons are not helpful for me.

Hi there,

Thanks so much for your feedback. I'm sorry to hear you don't feel the program will work for you at this time. We do recognize that the program may not be suitable for every situation.

I did want to mention that, depending on how far you got into the program, there are techniques introduced in later sessions which can be practiced to help you get back to sleep faster (when your children allow that).

We also have a Guide surrounding parenting and sleep, which may be of interest, if you'd like to check it out:

If there's a time in the future when you feel you might want to give the program another try, or if we can help with anything else, please let us know at We're always happy to assist!

All the best,

Sleepio Team

This app has saved my sanity!!!

I’ve been dealing with insomnia for the past few months. My doctor recommended Sleepio when I came in for my annual checkup and expressed dismay about my poor sleep and how it was affecting my physical health. I was an exhausted and anxiety-ridden wreck.

The Sleepio support team I sent an email to asking how I could get started were so kind, empathetic, and professional. No matter what question I had about how to sign up or any kind of technical question they helped me right away.

The program can be accessed on the app or on the website, which the latter seems to offer more stuff to check out than the app, like a whole Community of fellow insomniacs who were also so supportive and helpful!!!

The program does require discipline and a willingness to apply many, if not all, of the techniques that are introduced and broken down for you each week. Three months ago, I was at a breaking point with my mental health and felt like a zombie with not being able to sleep. Now, I feel like I have a new lease on life. Sleepio is amazing. Thank you!!!!!

Incredible program but mediocre user experience

I get why there are some really negative reviews for this - the app itself is clunky especially on first use (just set yourself up on a computer). But, for anyone that doesn’t just have a hard time sleeping but has an actual debilitating sleep disorder (🙋🏼‍♀️) this program is incredible. You should use it in addition to your current treatment plan, which is what it’s designed for. On the developers website, you can read the reports on how the app & program was developed, and what the empirical efficacy has been, which is seldom available for other apps of this nature.

Hi there - Thanks for your feedback we truly appreciate you taking the time!

I'm glad you were able to put the program to work well for you but am sorry to hear you felt the app experience wasn't great. Happy to say, though, that there are changes underway for the app that I think you'll be pleased with when released! It will be some time yet, but if you'd like us to get in contact with you when the next version is released, please shoot us an email to and we'll be happy to update you at that time.

All the best,

Sleepio Team
