derDennis Voidcaller is still in work with just two people that’s a designer and programmer. So every bug and issue can be fixed only by one person.
try to make an app alone maybe, without like anyone who could help you, as they do with Dialer for us. Assuming you’ll be living life as every normal person, have other home & work duties and the app is just an enthusiastic thing that can’t have your whole life cause you won’t be paid for this. And then complain about the feedback you’re not getting on your issues.
