To follow your brand identity and long-term business goals you must conceptualize your product ideas to build usable and appealing designs, make complex projects look simple and materialize your ideas through practical UI design solutions (more information here https://joinsoft.com/services/ui-ux-design-services/) and engaging user experiences. Only this will help you to achieve your goals.

I agree. Today there are lots of different apps of this kind. And it's not hard to create them, actually. But if, for some reasons, you can't do it yourself you can get a dedicated team of mobile app developers to build such app. They will not only create app but also make UI/UX design of it to help you beat competitors.
