To build a bakery app, start by defining its purpose—whether for online ordering, delivery, or customer engagement. Choose a tech stack like React Native or Flutter for the frontend and Node.js or Django for the backend, with Firebase or MySQL for the database. Design a user-friendly UI/UX with features like an interactive menu, order tracking, payment integration, and loyalty programs. Develop core functionalities such as product catalog, cart, secure checkout, and real-time notifications. Ensure data security, compliance, and seamless third-party integrations for payments and delivery. After thorough testing, deploy on App Store & Google Play, and market using SEO, social media, and app promotions to attract customers. Would you like help with cost estimation?
