How to Build an App Course

Lesson 1 • Defining Your App Idea

Teaches structured techniques for shaping a raw idea into a buildable concept. Directly prepares students for planning and scoping work ahead.

Lesson 2 • Understanding the App Ecosystem

Covers the types of apps, platforms, and the roles that bring them to life. Sets the context for every decision made throughout the course.

Lesson 3 • Choosing the Right Development Approach

Compares no-code, low-code, and full-code paths based on skill level and project needs. Helps students commit to the approach best suited to their goals.

Lesson 1 • Defining Features and MVP Scope

Teaches how to prioritise features and define a minimum viable product. Prevents scope creep and keeps the first build focused and achievable.

Lesson 2 • Mapping User Flows and Journeys

Covers diagramming how users move through the app from entry to goal completion. Reveals gaps in logic before any design or code is produced.

Lesson 3 • Writing a Project Brief and Timeline

Structures the app concept, scope, and schedule into a single reference document. Aligns expectations and serves as the north star throughout the build.

Lesson 1 • Core UI Design Principles

Introduces visual hierarchy, spacing, colour, and typography as applied to app screens. Builds the design vocabulary students use throughout all subsequent design work.

Lesson 2 • Design Systems and Component Libraries

Introduces reusable components, style guides, and design tokens for consistent UI. Prepares students to hand off designs efficiently and maintain visual consistency at scale.

Lesson 3 • Building a Clickable Prototype

Guides students through linking wireframes into an interactive prototype for user testing. Produces a tangible artifact that validates design before any code is written.

Lesson 4 • Wireframing App Screens

Teaches low-fidelity wireframing to lay out screen structure before visual design begins. Saves time by resolving layout issues early in the process.

Lesson 1 • HTML and Screen Structure

Covers semantic HTML elements and how they form the structural skeleton of any app screen. Directly enables students to translate wireframes into coded layouts.

Lesson 2 • Styling with CSS

Teaches CSS selectors, the box model, flexbox, and responsive design techniques. Enables students to match their coded screens to approved design specifications.

Lesson 3 • Connecting UI to Data

Shows how to bind dynamic data to UI components and handle loading and error states. Completes the frontend layer by making screens reflect real application data.

Lesson 4 • JavaScript for Interactivity

Introduces variables, functions, events, and DOM manipulation to make screens interactive. Bridges the gap between static layout and a working, responsive interface.

Lesson 1 • File Storage and External Services

Covers integrating cloud file storage and third-party services via APIs. Extends backend capabilities without building every feature from scratch.

Lesson 2 • User Authentication and Authorisation

Implements secure login, registration, and role-based access control in the backend. Protects user data and restricts features to authorised users only.

Lesson 3 • Backend Architecture Overview

Explains client-server communication, REST principles, and the role of a backend in an app. Gives students the conceptual foundation for every backend decision ahead.

Lesson 4 • Building API Endpoints

Teaches how to create CRUD endpoints that the frontend calls to read and write data. Produces the core interface between the app's UI and its data layer.

Lesson 1 • Bug Tracking and Regression Prevention

Introduces bug tracking workflows and regression test suites to prevent fixed issues from returning. Establishes a sustainable quality process for ongoing development.

Lesson 2 • User Acceptance and Usability Testing

Guides students through running structured sessions with real users to validate the app. Surfaces usability issues that automated tests cannot detect.

Lesson 3 • Debugging Techniques and Tools

Covers using browser dev tools, breakpoints, and logging to locate and fix bugs efficiently. Reduces time lost to guesswork and builds systematic problem-solving skills.

Lesson 4 • Types of App Testing

Distinguishes unit, integration, end-to-end, and manual testing and when to apply each. Frames the full testing strategy students will implement throughout this chapter.

Lesson 1 • Post-Launch Monitoring and Hotfixes

Introduces error monitoring, uptime alerts, and rapid hotfix deployment after launch. Keeps the app healthy and users satisfied from day one of release.

Lesson 2 • Submitting to App Stores

Covers the end-to-end process of packaging and submitting a mobile app for store review. Prepares students to meet store requirements and pass the review process.

Lesson 3 • Deploying a Web App

Walks through deploying a web app to a cloud platform using a CI/CD pipeline. Produces a live URL students can share immediately after completing this section.

Lesson 4 • Hosting and Infrastructure Options

Compares cloud hosting models and helps students select the right infrastructure for their app. Connects infrastructure choice to cost, scalability, and maintenance effort.

Lesson 1 • Analytics and User Behaviour Tracking

Teaches how to instrument an app with analytics to capture user actions and retention metrics. Turns raw usage data into actionable product insights.

Lesson 2 • Running Product Experiments

Introduces A/B testing and feature flags to validate changes before full rollout. Reduces risk by letting data decide which direction to take the product.

Lesson 3 • Collecting and Prioritising User Feedback

Covers in-app surveys, support channels, and review mining to gather qualitative feedback. Balances quantitative analytics with the human context behind the numbers.

Lesson 4 • Building a Product Roadmap

Guides students through translating insights and goals into a prioritised, time-bound roadmap. Closes the course by connecting technical work to long-term product strategy.
