Am I the only one that thinks anyone could hack up something like that in a few hours tops? Like most apps 95% of it is probably trivial, and then there's that 5% where you spend almost all of your time. In this case it's probably the integrations with other services and making a system that enables users to glue them together with rules in an intuitive way. That is not simple, especially if you're trying to work with lots of third parties rather than just the big ones. You probably could hack together a working app in very short amount of time, but that's true of everything. Making it robust, secure, user-friendly, and maintainable is where the value lies, and that takes time.
