App developers usually register in classes 9 and 42. Class 9 includes the downloadable software as a product, while Class 42 covers access to the software as a service. Keep in mind that a developer may also apply to other relevant classes specific to the app’s function, its industry, and to potential licensing and merchandising arrangements.
