I have been building a small app and I want to launch but I am continually unhappy with the aesthetics. I know enough to do a basic design but my focus is mostly backend.<p>Do I launch the product early and then work on UI or do I spend time on UI and delay the launch?
It depends on your audience and the competitive options. If solving a unique problem for highly technical users you may be able to address UX later. If your audience are consumers then the experience is everything...almost.
