Low-fidelity prototyping is about taking a rough concept and trying to prove (or disprove) its effectiveness because there’s not much use in designing something to completion without ever considering whether the design offers an optimum user experience.

An app prototyping is the stage where a client idea is verified for its mobile app feasibility. Designer and engineer work together to create a low-fidelity prototype which accommodates all client requirements and satisfies mobile app navigation and design concepts. In stunntech we usually creates a rapid prototype within 5 days of requirement gathering. The prototypes are then sent to clients for validation in the form of both flow chart and an Invision demo. Flow chart will be a pdf document which client can analyse for all the functionalities he needs to address in the app and Invision demo can be used for getting an idea about the actual app navigations. Invision demo can be also used for app pitching, investment and client gathering.

Why Rapid prototyping?

The most simple answer to this question will be - to save time and money. Its done within one week of time and is built considering all the features needed with basic design only. So client can actually review it to make decisions even before starting the actual app development. The requirement changes that occurs during the app development can consume a lot of time. So reviewing, modifying and finalising the app feature using the low-fidelity prototype can help in getting a solid plan for the entire app development and delivery.

Design tools:

Sketch

Sketch is a digital design toolkit built to help you create your best work — from early ideas, through to final assets. Sketch has built in mobile resolution artboards and mobile UI elements which makes static screen designing much simpler.The best part is that all the designed elements are in vector format and can be exported to the necessary resolution and type.

Invision

Invision is what converts static screens into clickable, interactive prototypes. We provide Invision links to clients which they can open to view the prototypes just like a normal mobile app with navigation. Even though sketch provides built-in prototyping from version 49, we prefer Invision because of its simplicity and export as link ability.

The revised prototype after all the client and investor suggestion is then converted to the actual app design which includes the graphical elements, color themes and other interactive app elements such as notifications, popups, warnings etc.
