Hello Marc-Oliver! The prototype itself can be up to 40 screens, but this includes different states like systems notifications, onboarding screens, and whatever else you need to tell a cohesive story with the prototype. The number of really essential screens is much smaller, but they need to be embedded in a story that makes sense to our testers.

Our rule of thumb: Number of cells in the storyboard * 3 = number of screens in the prototype.
