Personal Knowledge Management Systems (PKMS)

At a small enough company they're often the same thing.

Also, on mobile, developers who make good, reliable, robust software are discouraged from making such things. There's a reason there are so few pieces of "finished" software on mobile. Because you'll invest months of your life into making an incredibly useful and functional tool, and a year later, the new version of the mobile OS will come out, and it'll be "In the new version we've decided half of the operating system calls your software depends on are insecure, and three of the permissions that are necessary for your app to work no longer exist. Have fun rewriting the entire thing", after which the developer very reasonably says to hell with it, and goes back to writing software for an ecosystem that doesn't break every single user space application on a regular basis.

So yes, just by working in the mobile space, you're already accepting trade-offs in making robust software by the very nature of the ecosystem.
