Rapid prototyping is an essential part of the mobile app development process. By allowing designers and developers to create an interactive prototype that closely reflects the user's experience with the final product, rapid prototyping allows feedback to be taken into account early on in the design process. This helps to ensure that the finished product meets all of the user's requirements before it goes into production, saving time and money.

The length of time it takes to create a rapid prototype will depend on the complexity of the app. However, typically a basic prototyping process can take anywhere from a few hours to days depending on how many stages of user feedback and design iterations are included.

Start-up apps require a prototype in order to validate their product concept before they invest resources into building it out. A prototype helps founders gauge the market’s interest in an app and allows them to test their ideas quickly and cheaply. By prototyping early on, start-ups are able to define their product’s features, identify areas that need improvement, and make changes more efficiently. Robotics designers also find great benefit in using prototypes for testing before releasing the final version of a product.
