Connect the app with order processing services.
We implemented integration data exchange for the catalog, cart, client profile, and orders. The app transmits selected items and delivery parameters, receives information from connected services, and displays it in the relevant sections.

Ensure real-time updates.
We used WebSocket to receive events from the server. The order status updates automatically: preparation, handover to delivery, and completion. Users do not need to reopen the screen or manually request an update.

Make dish selection fast and convenient.
We developed a catalog with categories and detailed dish cards featuring photos, ingredients, nutritional value, and add-to-cart functionality. A sticky panel displays the order total and allows users to proceed to checkout directly from the catalog or product card.

Refine the smoothness of the mobile interface.
We configured animations for opening cards, pop-up windows, and transitions between states. We linked visual feedback to user actions so that adding a dish, modifying the cart, and switching sections are perceived as consistent and intuitive.

Integrate address and delivery method selection.
We added a map, address input, and a toggle between delivery and pickup. The checkout process displays delivery terms and the minimum order amount. Addresses are saved in the user profile, simplifying future orders.

Create a user profile for returning customers.
We implemented phone number login with a verification code. We combined orders, saved addresses, settings, and personalized promotions. We included a notification permission request to keep users informed about their orders.

Account for kitchen operating limits and feedback.
We prepared distinct states for a closed kitchen and temporarily paused order acceptance. The app explains the reason for the restriction and suggests an available action. The order screen includes support contact options and a service rating feature.
