Cost Calculator


Development costs for the different platforms are comparable. Choosing two platforms therefore doubles the costs.


For iPhone and iPad


For devices of Samsung, Sony, LG.., etc

Windows (Phone)

For devices of Nokia, Microsoft.., etc


The cost is directly related to the quality. Highly successful apps are often of a high quality.

Low X0.5

Most things work but the app isn't very attractive and crashes every now and then. There's almost no documentation and code quality is bad.


Everything works and the app's interface conforms to the usual conventions. The code is solid and the documentation sufficient.

High X2

Everything works perfectly and quickly. The app is nice to look at and has great usability. The code is modern and clean; the documentation complete and easy to understand.

Number of Screens

The number of different views is a good indicator for the total app size and is used as base value for calculation. Example: An app with an overview, a list view and a detail view would require 3 screens. A typical value for an average app would be 10.


Custom controls

Using the system-provided controls is the easiest way. Apps that don't exactly follow the platform's design standards require custom controls

If your app handles sensitive information, all aspects of your app are influenced by security considerations.


Hightened X1.3

Supported OS versions

Supporting more OS versions increases the potential user base but increases the costs for development and maintenance

One X0.7

Only the most recent version is supported (coverage of ~40%)


Besides the most recent version, the previous one is supported as well (default; coverage of ~75%).

Three X1.5

The most recent and the two previous versions are supported (coverage of ~90%).
