When you’re new to the market either its experience (ui/x) or the product’s problem-solving capability are the main factors that are going to define the future. Even if your product looks bad, if it solves the problem, people might stick for a few days or even months. But after a certain time, you have to fix the experience issues to keep them happy. Otherwise, when you try to scale, this will be the main roadblock. It doesn’t have to be something extraordinary. It should feel fresh and simple. This is what I learned from my experience at a start-up.

List this app in some startup marketplace to sell. See if there are any buyers. If yes - you know.
