Most of that site reads as a "trust us, sound makes you heal!" I don't see a single thing there that tries to explain the correlation between bumping your brain with sound and "restoration". It doesn't explain what it restores, why it works better than nothing.
Honestly this website doesn't seem to even be trying to sell anything. "Help your sleep" how? "doesn't make you sleep longer" but what does it do instead? Do I feel more restored when I wake up even with a shorter sleep time? It's not even trying to sell me on a specific outcome that I John Everyman is facing.
Snake oil things are typically very light on details and this site is also light on details. Maybe it's a victim of form over function? The site's design looks nice but has very low information density.
Fair criticisms. However, there are FDA limitations on what you can say regarding devices that both measure and affect biomarkers and neuromarkers while the user is unconscious.
This is why we describe the neural function of sleep, but can't specifically get into details regarding increases in slow-wave activity, 15% decrease in early night cortisol, 14.5% increase in HRV, etc etc. We can link to the research, but can't say "this is what we do".
We are relying on user testimonials, which we are gathering through our beta testing and beyond.
At the same time, we do describe the "clearer thinking", "immune function", "stress" etc about half way down the page.
It's something we will continue to get better at.
I understand your subscription model but I honestly hope you don't have large backend costs.
If the device came with a year free, or even a 6 month subscription, sure. But over $500 for a sleep aid is asking a lot.
The back-end costs aren't high.
We decided to go with a low device cost and subscription to make it cost effective to purchase when finances allow us to get to a monthly instead of yearly subscription.
