Wireframes & Design — Planning Before You Code

Imagine building a house without a blueprint. You would end up tearing down walls and rebuilding rooms constantly. The same is true for apps — if you start coding without a plan, you will waste time building screens that do not work well together. Designing first lets you: - Experiment with different layouts quickly (on paper, not in code) - Spot problems before they are expensive to fix - Show your idea to others and get feedback early - Know exactly what you need to build Professional developers spend 20-30% of their time on design before writing any code.

A wireframe is a simple sketch of your app's screens. It shows the layout — where buttons, text, images, and menus go — without any colors, fonts, or visual design. Think of it like the skeleton of your app. Just boxes, lines, and labels. It is intentionally ugly so you focus on how the app WORKS rather than how it LOOKS. For each screen, draw: - A rectangle for the screen - Boxes where images will go - Lines where text will go - Rectangles for buttons - Arrows showing which screen leads to which You can wireframe on paper, a whiteboard, or free tools like Figma or Excalidraw.

A user flow maps out how someone moves through your app from start to finish. It is like a flowchart of screens. Example user flow for a quiz app: 1. Home Screen -> Click 'Start Quiz' 2. Quiz Screen -> Answer 10 questions 3. Results Screen -> See score and answers 4. Results Screen -> Click 'Try Again' -> Back to Home Mapping this out helps you make sure: - Users can always get where they need to go - No screen is a dead end - The most important features are easy to find - The flow feels natural and not confusing
