  • Mobile apps provide easy access to your products or services 24/7, which is especially beneficial for businesses with online sales or services.
  • Customers can browse, shop and interact with your business anytime and anywhere.

Before building an app, another critical question that comes to business owners’ minds is how they can validate their mobile app idea. Currently, there are three ways available to legitimize an app idea:

  • Proof of Concept (POC): Also known as Feasibility Test, this is the fastest and the most accurate way to verify the feasibility of your app idea and its targeted audience.
  • Prototyping: It’s a kind of user research to determine how your mobile app will be functioning in real. In other words, it’s a visualization of your app’s working in the market.
  • Minimum Viable Product (MVP): This is a usable yet minimal version of your app to release and test in the market. An MVP helps your development team identify the app’s core functionalities, value proposition, user experience, and responsiveness.

Android or iOS: which platform should I build my app for? The best answer to this question is “for both.” Android has a worldwide market share of nearly 85%; on the other hand, iOS holds a market share of almost 61% in the US alone. However, it again depends on your targeted audience, whether you want to develop a custom mobile app for Android or iOS or both.

To be more specific, if your target audience is global, you should opt for Android app development. But if your target audience is the United States only, you should consider developing a custom mobile app for iOS. Go with both platforms if your target audience is both the US and global.

By having a Mobile App you are creating visibility for your company. A mobile app provides your business with a dedicated presence on customers’ smartphones. This constant visibility can help keep your brand top-of-mind when customers are making purchasing decisions.

In the product design world UX design concerns a users journey and experience with a product and includes identifying and solving user problems. On the other hand, UI design is all about creating intuitive, aesthetically-pleasing, interactive interfaces.

In our experience, one of the biggest mistakes people make when creating an app is failing to user test. Not testing your assumptions and failing to put your designs in front of users before beginning the development process is usually a recipe for disaster. In these cases it’s not uncommon for teams to spend a great deal of time and money developing features that end up falling flat with users.
