Frequently asked questions

What is interactive prototyping?

Interactive prototyping is the process of creating clickable, navigable mockups that simulate how a final product will look and behave. Unlike static designs, interactive prototypes allow users to click through screens, trigger animations, and experience user flows as if using a real application. These prototypes are essential for user testing, stakeholder presentations, and guiding development teams with precise interaction specifications.

How much does it cost to have a prototype made?

How long does it take to create an interactive prototype?

What's the difference between low-fidelity and high-fidelity prototypes?

Can you create prototypes for both web and mobile applications?

Do you conduct user testing with the prototypes you create?

What tools do you use for interactive prototyping?

Can prototypes be used to pitch investors or secure funding?
