4. Develop consistent UX.If you want to get users hooked on your app, you have to provide an experience that helps facilitate what your app is offering your users. Mobile marketing analytics research company Localytics noted in a study that only 21 percent of people who download apps only use the app once. So, it's important to focus on taking steps to retain users and understand their behaviors.With a prototype, you have the power to observe user interaction with your app. You can study user behaviors early on in the development process and make adjustments to your app to improve their experiences. For example, you can change the font of a button's text if you notice that users click the button more often. This helps to improve their experience and encourage engagement with your app.5. Drive stakeholder acceptance with a proven concept.When you're trying to convince important stakeholders, such as venture capitalists, angel investors or even crowdfunding audiences, to invest in your mobile app, it's challenging to get them to buy-in to your concept without a visual, working prototype.But with an app prototype, these crucial stakeholders get a clickable, interactive app they can use and test. It helps to justify funding since it reduces the risk of uncertainty and helps your audience visualize the potential profit your app can bring.
