If you want to develop an app, you should start out by thinking about how to make the app that you want to develop successful. There are now thousands of apps on the marketplace, so you really need to make sure that quality control is at the top of your list as you go through the process of creating the technical side of the app.
#1 Be As Specific As Possible With The App's Function
As you develop your application, one of the most important things you can do is make sure that you keep your application as specific as possible. Your application should be designed to deliver and enhance your user's life in one specific way. Don't try to add too many options and choices onto your app. Pick a specific task and market that you want your app to appeal to, and then do everything you can to make your app the best it can be for that specific task and market. Creating a singular and focused application will help ensure that your app is easy to use, reaches the desired market, and doesn't get bogged down and become difficult for the user to use.
#2 Base Your App On The Real World
People are drawn to applications that make sense to them and that correlate with experiences that they have in the real world, which is why applications such as sticky notes or applications that track calories are so popular— they are similar to tasks that people already engage with in the real world.
Make sure that your app connects and draws on real-world applications. Your app should make it easier to do something that people already do in the real world or provide assistance with something they would want to do if they had the tools to do so in the non-electronic world. Make sure that your application meets a needs and fits how someone would want to meet that need.
#3 Convenience Is Key
Third, make sure that no matter how you design your application, it is convenient to use. An application that is not convenient to use is going to get downloaded, used a few times, and discarded to the waste bin. If you want your application to engage users for the long term, it needs to be easy for them to use once they open it up. Really think about how it would feel to be a user of your app, and pull it up on your phone when you are on the go and out and about in the real world.
Test out your app in a real-world setting with testers to make sure that it is easy to use in the situations that one would want to use it in. For example, a food tracking app should be easy and quick to use while preparing and eating food.
If you want your mobile app to succeed, make sure that you addressing a specific need for a specific market in a real-world way that will be easy for your target audience to use.
