With Full Sleep, the app provides daily lessons about sleep and skills that can help with sleep. In the app, participants also record information about each night's sleep in their sleep log. Every seven nights, they also complete the Sleep Needs Questionnaire. At the beginning, middle, and end of the study, they additionally complete the Insomnia Severity Inventory in the app. At the end of every week, a sleep schedule and weekly summary are calculated via automated formulas. The app also contains access to messaging a coach. The intent of coach access is for participants to ask questions about their daily lessons and application of the skills and to feel supported and accountable.

The REST (Radar Enabled Sensing Technology) device in the Full Sleep program uses radar to passively track sleep patterns and nighttime awakenings. It also offers white noise options and audio guidance for relaxation techniques and stimulus control.

Path to Better Sleep is a self-management tool for insomnia. It is available as a web-based program at https://www.veterantraining.va.gov/apps/insomnia/index.html#dashboard. Path to Better Sleep is intended to be completed over six weeks, and includes weekly educational lessons about sleep which include videos, visual depictions, and interactive activities, in addition to sleep check-ins (e.g., knowledge checks, self reflections about sleep). It also includes sleep logging. Participants in this condition will be asked to share their sleep log weekly via email, as Stanford and Koko Labs do not receive access to the data.
