The idea behind a flower shop app is to create a convenient platform that allows people to order flowers online, browse the store's selection, receive information about products and services, and have flowers delivered directly to their home or office.

The problem this app solves is that many people don't have the time to visit flower shops in person and don't always know which bouquet or arrangement to choose. The app allows them to order flowers quickly and conveniently, either by consulting with a specialist or choosing from a selection of pre-made bouquets.

Features and details of a flower shop app may include:

1. A catalog of flowers and bouquets with descriptions, photos, and prices.
2. The ability to create your own custom bouquet.
3. Online consultation with a florist for assistance in choosing flowers.
4. The ability to specify a delivery address and delivery date.
5. Order payment through the app.
6. Order status tracking and progress notifications.
7. Customer reviews and ratings.

Key features of a flower shop app:

1. Browse and select flower selections.
2. Create a custom order.
3. Online consultation with a florist.
4. Place an order and pay.
5. Track order status.

Thus, a flower shop app will help make the process of choosing and ordering flowers more convenient and accessible for customers, and will also increase the store's competitiveness in the flower industry.
