The study is a single-blinded randomized waitlist controlled trial that aims to assess changes in objective and self-report sleep improvement through use of a dynamic and personalized sleep improvement smartphone app and advice engine in those with poor sleep (i.e., subclinical threshold insomnia) when compared to a waitlist control group after 6 weeks and 12 weeks.


Subclinical sleep dysfunction has a multitude of causes (e.g., environmental, cognitive, behavioral, or physiological) and symptoms (e.g., long sleep onset latency, short sleep duration, elevated wake after sleep onset and nighttime awakenings, poor sleep quality). A personalized and dynamic sleep improvement intervention tailored to an individual's lifestyle and specific needs may therefore be required to help nudge those with poor sleep towards sleep-promoting behaviors and attitudes. Digital and mobile health platforms are also highly scalable and cost-effective, thus allowing for widespread implementation across larger subclinical populations.

The purpose of the present study is to conduct a single-blinded randomized waitlist controlled trial to evaluate a novel smartphone application, Dein Schlaf. Dein Tag. powered by SleepScore, designed to both objectively measure and improve sleep. The Dein Schlaf. Dein Tag. app features a validated sonar sleep measurement tool and also provides dynamic and personalized sleep advice founded in the principles of cognitive behavioral psychology and sleep hygiene, offering a non-invasive and non-pharmacological behavioral intervention designed to improve sleep and circadian functioning in those with common sleeping difficulties. Participants will be randomly assigned to the sleep improvement app intervention or a waitlist control group. Online assessments on validated sleep and preventative health measures will take place at baseline, 6 weeks, and 12 weeks.
