Unfortunately, even the best projects in the world can fail due to some unpredictable factors that you can't influence at all. That's why good luck is also one of the components of your general success. However, it doesn't mean that you should rely only on it. Vice versa. You still should work hard in order to be sure that you have done everything that is possible from your side. To make sure that people will like your app and that your audience will be actively growing, first of all, you need to clearly understand who will be your target group, and analyze their needs and preferences. Moreover, you should deeply analyze market trends in order to understand what features are essential for a dating app today. It is also important to define what will be unique about your app (later, your marketing strategy should be based on this uniqueness). And of course, the quality of your software product should be outstanding.
