About this app

Learn how to sleep again with the award-winning mobile app for insomnia started as a venture at Harvard Innovation Labs, and developed in collaboration with sleep psychologists, therapists, and researchers. Looking to improve your sleep permanently? Any program can tell you to cut coffee, use blue-light filters or meditate. But the truth is much of the generic advice on the internet doesn’t work for people with insomnia. Stellar Sleep is different. Stellar Sleep uses the #1 science-backed approach for improving sleep that is personalized to your needs and simply works. We empower you to live a healthier and happier life by better understanding yourself and your brain, so you can wake up every morning feeling refreshed and ready to tackle the challenges of the day. Our results speak for itself. We have helped over a thousand patients fall asleep faster and stay asleep longer using psychology. Over 80% of our users see a dramatic improvement in their sleep in less than 4 weeks. Our evidence-based program takes only 5 to 10 minutes a day, and includes topics around: * Stimulus control * Cognitive restructuring * Undergoing sleep restriction therapy * Building strong sleep habits * Calming down a racing mind * Relaxation techniques * And much, much more In addition to our core sleep curriculum, you’ll have access to the following features: * A comprehensive library of nature sounds, breathing exercises, progressive muscle relaxation exercises, bedtime stories, sleep music and guided meditations to help you relax and unwind. * Track your progress, better understand your sleep and stay on top of trends with our sleep diary. * Connect with wearables through the Health App. * Gratitude and worry journaling. * 30 night challenge for those who have reached their sleep goal and want to maintain it. * A deeper dive into other mental health challenges. * Strategies for creating lasting behavioral changes in other aspects of your life.
