Description:

This was a randomized, double-blinded, sham-controlled trial. Overall, 68 subjects were randomized into the following groups:

• WELT-IP group: WELT-IP (insomnia digital therapeutics) use

• Control group: sham app use Subjects in both groups continued to receive their clinician-directed standard-of-care treatment for insomnia, if applicable, including pharmacotherapy. After screening of sleep diary, subjects were randomized and in WELT-IP group used WELT-IP and subjects in control group used a sham for a period of 6 weeks.

Secondary	Change from baseline to week 7 (post-treatment) of Sleep quality (SQ)	Sleep quality ranges from 1 to 5, where higher score indicates better quality of sleep.	7 weeks
Secondary	Change from baseline to week 7 (post-treatment) of Sleep onset latency (SOL)	Sleep onset latency is evaluated as the time it takes a person to fall asleep after going to bed.	7 weeks
