Add it to the pile. I think this is an important issue, but I don't understand why devs are compelled to create apps when the goal is just telegraphing information, and you only need to do that once. That's what books are for. I guess you'd have to count on there being a demographic that only wants to absorb information through apps.

Much of the content is (and ought to be) freely available information anyway, at least for boilerplate CBT-i (see e.g. https://insomniasos.net/). Obfuscating what is the size of a buzzfeed article behind payments and apps to make a buck is absurd.

Seeing a professional is one option, but ymmv. GPs don't seem to know much about this and reflexively prescribe pills because that's what people want and expect of them. Sleep specialists can be good, but the source material behind their approach can be limited and dated (like CBT-i itself). What I did is read a pile of research articles (maniacally at first), and books. It's not for everyone, but you'll find more useful information than in glorified advertisements in google searches.
