Both Stellar Sleep and Sleepio are based on behavioral psychology. Sleepio is a weekly program (I believe you spend an hour each week). From our experience and also through user interviews, we found that it's easier for patients to follow a daily program (we offer daily bite-sized modules so you don't have to spend more than 5 - 10 minutes a day).

Also good point! We do delve into sleep hygiene - that being said, our target audience is people with chronic insomnia (insomnia 3+ nights per week for 3 months or longer). While common advice such as “avoid caffeine after 4pm”, “limit alcohol in the evening to no more than 2 drinks before 7pm” or “minimize the use of blue-light emitting devices an hour before sleep” are helpful, there is little evidence that sleep hygiene alone is sufficient to treat chronic insomnia.
