Prototyping and subsequent user testing perhaps yielded the most dramatic design improvements, which ultimately contributed towards app screen designs intended to represent a product ready for publication.
These iterations at this advanced stage carry extra significance since the app visual design is the most tangible representation of a product that could be implemented.
The high fidelity wireframes, in particular, shifted from on-boarding guidance with coaching throughout the app experience to a simpler presentation at the entry landing page, where users can decide whether they want to read more about feature details at that point, or they can just go ahead and sign up or log in.
The intent with this design change is to permit greater user autonomy while simultaneously reducing friction in the user flow, especially at the beginning.
