Must-have features of flower delivery apps
Customized note
Allowing customers to attach a personal message to the flowers they've bought could be a fun feature to include in an on-demand flower delivery app. Users will write a note while placing an order, which may then be printed and delivered along with the flowers or arrangement. This function offers a personal touch while also assisting users in communicating their messages.

Scheduled delivery
This feature allows your customers to choose whether they want their item delivered right away or at a later date and time. They can choose the date and time for the flower delivery and deliver it exactly when they want it.

Real-time tracking
Allowing your consumers to track their orders in real-time is another important feature. From 'Preparing the order' to 'Order shipped' and 'Order delivered,' they must be updated about everything. Customers can then track the delivery executive's movements using the florist app's geolocation feature while on his way to deliver their order. It allows customers to know how long their order would take and the exact date and time of delivery.
