CBT-i Coach is for people who are engaged in Cognitive Behavioral Therapy for Insomnia with a health provider, or who have experienced symptoms of insomnia and would like to improve their sleep habits. The app will guide you through the process of learning about sleep, developing positive sleep routines, and improving your sleep environment. It provides a structured program that teaches strategies proven to improve sleep and help alleviate symptoms of insomnia. CBT-i Coach is intended to augment face-to-face care with a healthcare professional. It can be used on its own, but it is not intended to replace therapy for those who need it. CBT-i Coach is based on the therapy manual, Cognitive Behavioral Therapy for Insomnia in Veterans, by Rachel Manber, Ph.D., Leah Friedman, Ph.D., Colleen Carney, Ph.D., Jack Edinger, Ph.D., Dana Epstein, Ph.D., Patricia Haynes, Ph.D., Wilfred Pigeon, Ph.D. and Allison Siebern, Ph.D. CBT-i has been shown to be efficacious for insomnia for both Veterans and civilians. CBT-i Coach was a collaborative effort between VA’s National Center for PTSD, Stanford School of Medicine, and DoD’s National Center for Telehealth and Technology. CBT-i Coach works with the Apple Health app and Fitbit.

Verdict
The clearest difference is review sentiment: CBT at 47% against Hypknowledge's 0%. CBT also leads on rating (4.6 vs 3.0) and ratings volume (11K vs 2). Hypknowledge's advantage is update cadence (monthly vs every 7 months) and iOS requirement (14.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
