Glad to see the mental health apps space expand. The problem with curative healthcare apps is that it's hard to make it a sustainable business without government fund or private partnerships. App success is generally linked with usage. The longer the people use the apps, the more successful they are. In the case of curative apps that's reversed. Your app is more successful if people don't need it anymore, which makes it hard to monetize. I hope you manage to overcome this challenge and wish you great success!

It might be interesting for you to follow the story of Quirk and how they had to pivot as a company: https://github.com/Flaque/quirk

Also an interesting read, their original Launch HN thread: https://news.ycombinator.com/item?id=20646918

I am not affiliated with them, their story is the first thing that popped in my mind when I saw this.

Thanks for bringing those up. We're certainly aware of Quirk and the story, although we haven't as yet talked to the founders in person. Their story is very relevant to this discussion.

The points about sustainability of business model are very relevant ones, which is why we have a long term aim of building software as a medical device, which is potentially distributable / reimbursable by healthcare systems / insurance. This also opens up potentially different payment models, which can be more sustainable.
