I don't see step #1 as "wear a sleep tracker". IMO that should be #1. I've been wearing sleep trackers since 2014 (first the MS Band, then Band 2, then Charge 2 and now Ionic after MS discontinued the band). So I have 5 years of data (approaching 2 thousand night's worth of data!), which makes analysis and recommendations and experiments far easier.
Maybe you do incorporate that later on in the flow, but I was surprised I didn't see it on page 1.
Think podcasts, long-form testimonials, what it's about, etc...
