  • “When I first bought your app, I thought it was going to be another purchase down the drain, but honestly I was willing to try anything. The way you broke things down into a step by step plan and told me exactly what to do every day was very helpful.

    Nowadays, my sleep is so much better. I can get about 7 to 7.5 hours per night (I was getting 3 hours before). ”
    From San Diego, California (28 years old)
  • “I’ve waited forever for an app like Slumber One. Even though I don’t actually have chronic insomnia, but I do struggle to fall asleep every once in a while (usually after really busy days at work and I’m also planning a move which takes up a lot of energy).

    Thanks for making an awesome CBT-I app that I can actually buy and use. I loved your program, and found it super easy to use and highly educational. It’s great how you help me understand the theory behind good sleep, then make it easy for me to put theory into practice. ”
    From Brooklyn, New York (37 years old)
  • “I went through a pretty traumatic life event that seriously screwed up my sleep. I’d always been a good sleeper before, and never thought that I would ever suffer from insomnia. I tried meditation, melatonin, sleep pills, oils, anything but none of that helped. I even mustered up the courage to try some of the prescription stuff, but that only worked for a short while before it stopped being effective, and my wife really didn’t want me on that.

    It was definitely a mindset shift when I first started using your program, and it was probably only 3 weeks into your program that I was totally convinced that my sleep was going to get a lot better. ”

Frequently Asked Questions

What is different about your program versus another sleep program?

Our sleep program was designed in collaboration with top sleep experts and is based off the latest research on CBT-I. CBT-I is clinically proven to be effective for insomnia, and our program is also personalized and tailored to your sleep data.

What is CBT-I?

Short for Cognitive Behavioral Therapy for Insomnia. CBT-I is effective with many types of insomnia, even showing potential benefits for patients who don’t meet the clinical criteria for insomnia. CBT-I is 3x to 5x more effective than sleeping pills in improving sleep. In fact, the American Academy of Sleep Medicine recommends that all adult patients receive CBT-I as a first-line approach.

How long is the program?

You'll receive a personalized program based on your sleep needs. Most of our users start seeing results in 2 weeks, and no longer experience insomnia within 4-6 weeks.

How old do I have to be to start your program?

The recommended minimum age for participation in the Slumber One program is 18.

Are there any side effects to your program?

CBT-I uses sleep restriction and consolidation, which may cause daytime sleepiness until sleep has been regulated. In general, CBT-I is safe for most people. However, CBT-I is not recommended if you have the following conditions or disorder:

  1. Any psychiatric disorders worsened by sleep restriction (e.g. bipolar disorder, schizophrenia, other psychotic spectrum disorders)
  2. Epilepsy
  3. Untreated obstructive sleep apnea

Anyone in a profession where they need to be alert or cautious to avoid serious accidents (e.g. long-haul truck drivers, long-distance bus drivers, air traffic controllers, operators of heavy machinery) should also consult with their health care provider before starting the program.
