Actually, they don't want an app at all. They want to just be skinnier so that they look more attractive to their significant other or potential mate.
> Likewise, they don’t want an app for general-purpose list-based collaboration. They want an app for smoothly collaborating in precisely the ways that collaboration works best in their organisation, whether that is list-based, project-based, chat-like discussions, whatever.
They don't want that either. They just want their boss to stop bugging them so they can feel autonomous at work and have their work mean something. And they want their work to go as fast as possible so they can go home to their kids and be good parents.

The biggest lesson that I've learned building products is that people don't want these products at all. But sometimes they find a product that they hope will help them become better at the things they actually do want.
People don't want to buy a camera. They want to be better photographers. So help them become better at what they actually want to do, and you'll find yourself selling more cameras.
That's something I try my hardest to stick to with Draft (http://draftin.com) and it's been working really well. I realize my users don't want yet more writing and collaboration software. But they do want to be better writers. They want more people reading their blog, or they finally want to tell their friends they finally published a book. So I constantly try to find ways for the app to help them get better. And not just the app, but I'll even have webinars, blog, teach my methods at writing, storytelling, getting more readers, etc. and now I have people paying attention to the things I make and sell.

For these apps of yours, they look like really great places to start from. I think you could do a lot on their homepages and on your blog helping people get better at what they actually want to do with these things, and you'll probably find they are paying more attention.
I'm happy to help brainstorm some more on this if it would help. Hit me up on Twitter (@natekontny) or email (nate.kontny gmail).
