You cannot survive in mobile market without the knowledge of its ongoing trends and technologies. It is just impossible. Deep knowledge of mobile application development leads developer to sense those issues which are often left ignored and at the end of the day, they turn out to be the only cause of failure.
There may be several issues that inexperienced developers can leave unnoticed. And because of this, any stage of mobile application development can fall down and become a problem. A very common problem is having an undeveloped idea. Many developers hurry to implement an idea without thinking about the market. The issue can also arise because of the wrong selection of development tools. An app can also fail if it is not based on suitable business model. Remember how Mark Zuckerberg batted heavily on HTML5 and how the app failed, and how they had no choice but to return to native app.
Now the company has completely overcome all the difficulties that HTML5 based app caused, but it was hard from them to do that. They had sufficient manpower to handle the entire course but a company with fewer people and limited resources can hardly recover to such failure. Maybe, the entire project is collapsed with huge losses.
So expert developers know how different designing, development and deployment related issues are resolved. Indeed it is strongly recommended that all these issues are resolved before the beginning of the project, but in case something goes unnoticed, then they also know how to settle it. Let us encounter top things which require extra care of developers.
The approach for input
Users do not have enough space in the displays of smartphones. They have to do every task in limited area. Expert mobile developers are aware of this fact and thus they choose the best of the input methods. Users just do not want to scroll page too long to go in the bottom. They want everything on a single page. The task like form-filling is not good for mobile devices but, if it is really important then choose an input method to fill fields that require minimum users-efforts.
UI and Usability
Only the apps with impressive design win the battle. In case your app fails in spite of having good functionality, consider you have failed to add the best of the user interfaces, usabilities, or user experiences to it. And users have hundreds of other choices. The first thing to consider is how user-friendly an app is. So it is expected to be better by design.
The technology of app development
You cannot randomly choose any mobile application development technology for your app. Separate technology is suitable for separate idea and thus you need to choose one accordingly. There are generally three app development technologies: native, mobile-web and hybrid.
You just cannot give your app away for free. If you have invested several valuable weeks in creating the app, you would probably want to make money from it too. But how will you do that? There are several methods of monetization and again, not all methods are suitable for all sorts of ideas.
