Mobile app investors are met with a plethora of pitches in their inboxes every day. Understanding how to build an app and launch a prototype for your mobile app can help differentiate your startup from the rest and give you a competitive advantage when pitching your app to potential investors.

• Understand The Problem.One of the first steps in creating a quality app is ensuring you have a problem worth solving. The problem could range from a corporate requirement, if you’re going after the B2B market, to something as simple as boredom
• Identify Key Functionality Requirements.Once you’ve identified the problem, start brainstorming product requirements. It’s easy—and quite fun—to list the hundreds of different features your app should have. And that’s exactly what you should do!
• Create Sketches Of The Primary Screens.After you figure out the highest priority features, start thinking through the user experience. One of the best ways to craft the user experience is to begin with a few rough sketches of how the primary screens should look and feel.
• Turn Your Sketches Into Wireframes.A wireframe is a low-fidelity, simplified outline of your product consisting of boxes, words, lines and sometimes descriptions. It’s meant to lay the framework of where your app will go rather than the final look and feel of the app.
• Turn Wireframes Into A Prototype.Prototyping not only makes your product more real for investors, but it also gives your testers the ability to get a real feel for what it would be like to use the app, and arms your developers with a better sense of the intended UX before finalizing the design.
• Translate Wireframes Into Final Designs.In each scenario, you will want to spend time talking to these people about your vision and gauge their ability to execute by reviewing their past work. Some designers use Sketch to create their app designs; others use Illustrator. When you have the final files, update your Invision or Xcode prototype to make it look and feel like it’s live.
