After 2 years dwelling in the indie hacking and buildinpublic. I realize that it's about marketing and not the idea. You can even sell peanuts online if you crackdown marketing. So what is the real use of all the apps? I think every app in the niche has value that it's more than enough to achieve what user wants to do.

I can pinpoint 100 habit tracker apps literally doing the exact same thing but able to make money.

What are your thoughts? Do you agree?
