The only way to develop and app is to start with an idea. You did that and vaultbook is the result. While some may like or dislike it is not the point. We all are allowed an opinion, that's where the impetus to forge ahead with your idea comes from. To say that you should not be a programmer is unjustified, pointless, and should not deter you from future projects. My opinion? The comment from oryman was inappropriate.
