No. I created an app in one of these (a year ago). I have 5 serious competitors. Each are decent apps that have been in the game longer than mine - mine is not necessarily better, just with a slightly different angle.
It has about $3.5k MRR, is still growing and I spend maybe 5-10 hours a month on it.

Also, I had no brand before that.
