I personally would not be able to convince myself that my side project's execution is /better/ than something MetaLab (or any of the many companies I admire) built, but certainly it would be better suited to my personal itches.

That is not intended to be a comment on your execution though, I don't know what you've built.

What I would try to do is refine the niche that I am satisfying. There are a ton of task management applications out there, which means that there is a large number of ways people like to track and do their tasks, which means that something that solves your particular problems very well is going to satisfy more.
