It is very tough to quote the exact app development cost until you have all the details of the project requirement. App development cost depends upon various factors such as type of app, features, design, functionality, third-party APIs, support, and maintenance.
There are three categories of application. Here is the app development cost breakdown :
Small-Sized app - Small-sized app has 6-10 unique screens. It only includes basic features and doesn't include many third-party APIs. A developer needs standard UI components, basic filters, a feed list, and map markers. The app development cost for a small-sized app is between $10000 to $25000.
Mid-Sized app - Mid-sized complex app has 20-25 unique screens. It includes more complex features than a simple app. App required a payment gateway, integrations, analytics, custom UI, real-time chat, and a simple backend server. The app development cost for a small-sized app is between $25000 to $50000.
Large app - The large complex app has 40 to 45 unique apps. It includes advanced-level functionality compared to the above two categories. App required features like geolocation, google maps, ads, data encryption, data streaming, different user roles, etc.
