I've been trying for months to get on Sleep.io as I suffer from chronic insomnia, and it has been one of the most frustrating journeys I've endeavored upon. They only provide their app to insurance customers that partner with them, there is no option to buy a subscription directly. Despite their marketing and outward "shoot us a message and we'll help you out" virtue-signaling, you quickly realize that you're just sending messages into the void. I tried so hard and offered to pay a subscription rate to try the service. Didn't even get a response.
It's the absolute worst of all worlds: being prevented from being able to use an app that I shouldn't need to talk to a doctor about or have the correct insurance for is unbelievably frustrating. Stuff like this terrifies me for our future.
