ScienceSoft as a reliable Windows app development partner:

ScienceSoft has worked with us to develop a library application for Windows, macOS, iOS, and Android. They suggested and implemented a multi-platform framework that minimized development costs. We have continued iterating on that application and adding new features over several years, and ScienceSoft's developers have been great at implementing the designs that we give them, as well as suggesting ideas themselves. They produce good code, they are quick to respond, detail-oriented, and a very good value for our money.

Costs of Windows Application Development

While a basic Windows app will cost just around $40,000 to develop, the price of developing an application of average complexity will reach the $200,000 margin and go beyond $400,000 for extremely a complex application.

As you see, the costs of Windows application development are highly variable, still there are the main factors that influence the project costs:

General cost drivers

  • Number and complexity of Windows application features.
  • Number of Windows versions supported or Microsoft devices targeted.
  • Location and structure of the project team.
  • Vendor’s pricing model (in case of cooperation with a vendor).
