So a while ago a i remembered one post from HN, it was some guy crawling google play store and keeping apps that were paid and people used them but had a low rating. He was selling this list, not sure if it was successful but i made something similar and updated

So far checking only 3 marketplaces, my crawlers found so far about 100k apps, the default filters show only the more interesting once (paid and low rating)

Its free.

I will add more and more marketplaces eventually. I will also try to add some social features, like "working as a team on some idea" and posting own ideas, but will see how it goes.

Feedback welcome

EDIT: i just see it on mobile, it does not look ideal. Will need to work on that hm.

EDIT2: just added pagination :), hope it works for you.
