Study Notes

Introduction

Mobile applications are projected to generate $233 billion in revenue by 2026
The number of apps released to the market grows daily
More mobile devices exist globally than people
Businesses are seeking mobile app development for various reasons:
- Creating new consumer-facing apps like TikTok or Zoom
- Optimizing internal processes with enterprise solutions
- Reducing expenses and improving efficiency

7 Key Steps of Mobile App Development Process

Strategy Development
Analysis and Planning
UI/UX Design
App Development
Application Testing
Deployment
Support and Performance Monitoring
These steps may vary for individual applications

Step 1: Strategy Development

Defining the strategy for the application
Understanding the application goals, capabilities, and business model
Considering important aspects like:
- Objectives
- Competitors
- Platform
- Monetization

Identify Objectives

Determining the application's primary objectives
- Identifying the problem the application solves
- Determining the target users
- Defining desired outcomes and results

Research Competitors

Analyzing existing or potential competing applications
Evaluating app performance (installs, reviews)
Identifying ways to differentiate from competitors
Understanding industry best practices and relevant industry mistakes

Select Platform

Deciding the target operating systems for application (Android, iOS, cross-platform)

Choose Monetization Method

Determining how the application will generate revenue including:
- In-app advertising
- In-app purchases
- Subscriptions
- Affiliate marketing
- Paid apps
Monetization depends on application type (dating app vs. game app)

Step 2: Analysis and Planning

Thoroughly analyzing application details before design and development stages
Identifying necessary application specifications

Functional and Non-Functional Requirements

Defining specific actions the application will perform (functional requirements)
Assessing quality and performance of the application (non-functional requirements)
Important in ensuring optimal user experience

Product Roadmap

Creating a plan to achieve intended application goals
Identifying top priority functions and features
Determining whether features can be added later on

Technology Stack

Identifying the necessary skills for mobile development project
Specifying whether the app is for iOS, cross-platform or multi-platform.
- Choosing suitable technologies for the app (Titanium, Xamarin, etc)

Step 3: UI/UX Design

Creating user-friendly, intuitive and appealing applications
- Ensuring smooth user experience
- Highlighting the importance of aesthetic design and usability for the application

Information Architecture and Workflows

Establishing clear rules for app structure and navigation
- Organizing app information in a clear and logical manner
- Creating workflow diagrams to track user interactions

Wireframes

Creating digital layouts for application functionality
Visual representation of application structure focusing on user experience and aesthetics to ensure intuitive, seamless application use

Style Guides

Developing design guidelines for brand consistency and harmonious look and feel
Determining design aspects in a single document including fonts, color schemes, spacing guidelines and other visual elements

Mockups

Creating final visuals by implementing design guides

Prototypes

Simulating user experience and complete app workflow
Detecting and fixing design and functionality flaws

Step 4: App Development

Breaking down app development into backend and frontend components

Backend

Creating databases and server-side objects that improve application performance
Utilizing appropriate programming languages, database engines, and hosting solutions

Frontend

Choosing from different development methods:
- Platform-Specific
- Cross-platform
- Hybrid

Step 5: Mobile App Testing

Evaluating if the developed application meets important criteria:
- Functionality
- Performance (responsiveness to user interactions)
- Security (data protection)
Testing application on various devices and operating systems
Extended Review: Testing the application with real users from focus groups to gain feedback

Step 6: Deployment

Employing various distribution models according to the application platform
Submission to app stores (Apple App Store, Google Play Store)
Private Distribution models

Step 7: Support and Performance Monitoring

Continuously monitoring app performance to ensure smooth user experience
Monitoring crucial application performance indicators (KPIs) including:
- App downloads
- Active users
- Average visit time
- Retention
- Churn
- Conversions
- Customer lifetime value
- Ratings
- Reviews
Addressing bugs and improving based on user input
