The development of an on demand food delivery app requires careful consideration of various factors to ensure its success. Here are some essential aspects to ponder before embarking on this journey:

Market Research

Begin with extensive market research to gain a deep understanding of your target market. Analyze local demographics, shopping habits, and preferences.
