You came up with a very good idea. It will be helpful for app users who want to have paid apps and developers who want to publish their apps using/for bitcoin. I visited your site and it looks good, mobile friendly too. I was searching for more info though. Are you planning to have a developer console too on your site, just like in Google Playstore?  Or maybe something like that so that developers who want to publish an app in the future can just go there. I also installed the app and it seems to be a good start. I know it's in beta and there will be more content soon.
