Rest

Rest is an iOS sleep app that delivers CBT-I based programs with a personalized sleep window, nightly log, relaxation tools and an AI sleep coach, designed with sleep specialists and offered with a free self-guided tier.

Rest is a sleep improvement app built around CBT-I, Cognitive Behavioral Therapy for Insomnia, the behavioral method that clinical guidelines commonly name as first-line treatment for chronic insomnia. Instead of offering white noise or sleep tracking alone, it targets the habits and thought patterns that keep sleepless nights going long after the original trigger, such as stress or a change in routine, has passed. The product is aimed at adults who struggle to fall asleep or stay asleep and want a structured program rather than tips. Its content was shaped by a group of advisors that includes a UCSF psychiatry professor who leads a sleep research laboratory, licensed therapists with CBT-I certification, and sleep medicine researchers. The site also points to peer-reviewed studies from ACP Journals, BMC and JAMA Internal Medicine as the evidence base for the approach. In practice, a new user takes a short quiz, chooses a program, and downloads the iOS app to receive a personalized protocol. From the first day the app provides a personalized sleep schedule, a nightly sleep log, science-backed education and relaxation techniques. A conversational coach called Rest AI handles daily check-ins: the user describes how the night went, and the plan is adjusted as the log builds up. The company says Rest AI is trained on current sleep research and guided by its specialists, and that many users notice improvement within two weeks. Among alternatives, Rest sits between general wellness apps that play sounds or meditations and human-delivered CBT-I, which requires a clinician and scheduled appointments. It offers a free self-guided tier with a sleep log, sleep window and education, plus a fuller coached program reached through the quiz. The homepage does not describe any medical diagnosis or treatment of sleep disorders such as apnea, so people with suspected underlying conditions should still consult a physician. Press mentions listed include Fox, Fast Company, The Curbsiders podcast and an Apple feature.
