The food delivery industry is heavily dependent on trends, and this means that you will need to make your app trendy to stay on top of your competitors. The best way to create an interesting app is to ask your customers what they would like in the future. Popular features such as smartwatch integration, social media integration, and virtual assistants are all good options to consider. You should also be very aware of your target audience's preferences, and document this data. The most important demographics to look for are age, gender, and nationality. Income is a major factor as well, and food delivery apps need to be relevant to it.
