Mobile app development

Mobile App Development Concepts

Introduction

  • Mobile app development is a process by which applications are created for mobile devices.
  • Typically involves writing software that works with a specific Operating System (OS), such as Android or iOS.
  • Development requires understanding and applying various programming languages, including Java, Swift, Kotlin, or JavaScript, among others.

Mobile App Design

  • A primary component of mobile app development, involving the visual layout and user interaction.
  • Graphics and UI elements of an app are determined during this phase.
  • Principles such as ease of use, simplicity, and intuitiveness take priority.
  • Attention must be paid to the app’s Usability and Accessibility to ensure it's easy-to-use for all users including those with disabilities or special needs.

App Development Cycles

  • The Software Development Life Cycle (SDLC) principles apply to mobile app development.
  • Planning: Identifying the aim of the app, gathering requirements, and conducting a market study.
  • Design: Creation of the User Interface and User Experience (UI/UX) layout.
  • Development: Writing, iterating, and testing the code.
  • Launch: Releasing the app on a platform, such as the Google play store or Apple app store.
  • Maintenance: Updating the app regularly according to user feedback and new features.

Mobile App Categories

  • Native apps: Developed specifically for one mobile operating system. Swift and Kotlin are used for iOS and Android respectively.
  • HTML5 apps: Based on the standards of web technologies - HTML5, JavaScript, and CSS. These apps are cross-platform compatible.
  • Hybrid Apps: Mix of Native and HTML5 apps. Built using cross-platform web technologies like React Native or Flutter.

Testing Mobile Apps

  • Testing is a critical part of the development process to ensure the app works as expected.
  • Different types of testing include Unit Testing, Integration Testing, Functional Testing, Usability Testing, and Performance Testing among others.
  • Focus on uncovering any bugs or issues before the app gets to the end-user.

Monetising and Marketing Mobile Apps

  • Monetisation is often achieved through strategies like ads, in-app purchases, subscriptions, or charging for app downloads.
  • Marketing strategies rely on app store optimization (ASO), social media advertising, content marketing, and press releases.
