What Are the Different Types of Mobile Apps?

There are three basic types of mobile apps on which the apps are developed. But so many people are confused in recognizing them. To let you know about this, have a look at their mentioned definitions.

Native Mobile Apps:

Native mobile apps are created to be “native” to the individual platforms, whether it’s Apple iOS, Google’s Android, or Windows Phone. The native platform is beneficial because it manages to optimize the user experience effectively and gives an amazing look and as it was developed particularly for the platform, it can work more swiftly and instinctually.

Hybrid Mobile Apps:

These apps can be fixed on devices just like native apps, but they also operate through web browsers. All hybrid apps are created by the HTML5 programming language. Though hybrid apps are not as quick or guaranteed as native apps, they have a greater capacity for streamlining the development process.

Web Apps:

Web apps are active or you can say that responsive versions of websites can operate on any mobile device or OS because they’re presented using a mobile browser. You are able to get the best and attractive user experience with these apps and you don’t have to download any particular app for accessing these kinds of apps.

How Much Time Does It Take to Develop a Mobile App?

For developing a mobile app, we cannot decide the exact time as it is based on many factors. But the estimated apps can take anywhere between three and nine months to finish, depending on the app complexity and the construction of your design. Every step in the process demands different amounts of time to finish, but the most time exhausting of these lead to include:

  • Composing a project in brief: 1 or 2 weeks
  • Studying your opinions with the developers: 4 to 5 weeks
  • Plan sprints: 6 to 12 weeks
