Hello!
The development cost of an app similar to Airbnb typically relies on the number of desired features and the total development hours dedicated to implementing those features. To provide a comprehensive breakdown, it is necessary to identify the essential features that should be included in the app, evaluate the time required to develop each feature, and consider the average cost associated with it. This average cost is generally contingent upon the hourly rate charged by the mobile app development company.
