Introduction

Learn how to improve the visual quality of your Woz app using better prompts and free design resources. Design is one of the first things users notice when they open an app. A clean and consistent interface helps build trust and makes your product feel more professional. You do not need to be a designer to create a great-looking app in Woz. With clear prompts and a few simple resources, you can guide Woz to generate a polished and consistent interface. This guide explains practical ways to improve the design of your app during the building process.

​
1. Set Your Visual Direction Early

One of the most effective design decisions happens before your first screen is generated. When writing your initial prompt, include a clear visual direction so Woz builds your app with a consistent style from the start. This helps prevent design inconsistencies later.

​
Weak visual direction

Make the app look clean and modern.

​
Strong visual direction

Clean white interface with a deep navy primary color and bright blue accent color for buttons. Rounded cards with soft shadows, simple typography, and a minimal layout. The interface should feel professional and easy to navigate. Providing a clear visual direction helps Woz apply consistent colors, layouts, and UI components across the entire app.

​
Helpful details to include

  • The overall color style (light, dark, minimal, vibrant)
  • Whether UI elements should be rounded or sharp
  • The tone of the interface (professional, friendly, minimal)
  • How spacious or dense the layout should feel
The clearer the design direction is at the beginning, the fewer adjustments will be required later.

​
2. Use Select Elements to Adjust Specific Components

If something in your interface needs improvement, avoid regenerating the entire screen. Instead, use Select Elements to modify the specific component that needs adjustment. Turn on Select Elements, click the element you want to update, attach it to the chat, and describe the change.

​
Example prompts

Button Make this button fully rounded with a stronger shadow and use a brighter accent color. Card Increase the padding inside this card so the text has more spacing. Heading Increase the font size and make the heading bold. Input field Remove the border and use a light background color for the input field.
Always describe exactly what should change. Instructions like “make this look better” usually produce inconsistent results.

​
3. Describe the Style You Want

Instead of writing technical design instructions, simply describe the experience you want the app to provide.

​
Examples

  • Minimal and modern interface with lots of white space.
  • Friendly design with rounded shapes and bright colors.
  • Professional layout with clear sections and structured navigation.
  • Clean dashboard-style interface with simple typography.
Using natural language like this helps Woz interpret the visual direction more effectively.

​
4. Keep Your Color Palette Simple

A common reason apps look unpolished is the use of too many colors. Limiting your interface to a small set of colors helps create a more consistent and professional design. If your app starts using inconsistent colors, you can guide Woz with a prompt like this.

​
Color consistency prompt

Apply a consistent color palette across the entire app. Use a clean white background, one primary brand color, and one accent color for buttons and interactive elements. Avoid introducing additional colors. Keeping your palette to three to five main colors usually produces cleaner and more balanced designs.

​
5. Free Design Resources

You do not need expensive tools to improve your app’s visual quality. Many high-quality design assets are available for free. These resources can help you add icons, illustrations, fonts, and logos to your Woz app.

​
Icons

Icons make navigation easier and help users quickly understand actions inside the interface.
  • UXWing – Clean SVG icons free for commercial use with no attribution required.
  • SVG Repo – Over 500,000 SVG icons and vectors.
  • Flaticon – One of the largest icon libraries available.
  • Ionicons – Open source icon set designed for mobile apps.
  • Iconoir – Large open source icon library with thousands of icons.
  • Tabler Icons – Over 5,000 free open source icons optimized for web and mobile interfaces.

​
Illustrations

Illustrations help improve onboarding screens, empty states, and marketing sections.
  • unDraw – A library of modern illustrations that can be customized to match your brand colors.

​
Fonts

Typography plays an important role in how your app feels. A clean and readable font improves usability and gives your interface a more polished appearance.
  • Hand of You – Create a custom font using your own handwriting, which can give your app a unique and personalized feel.

​
Logo Tools

If your app needs a simple logo, these tools can help create one quickly.
  • Canva – A beginner-friendly design platform with many logo templates.
  • Adobe Express – An AI-powered logo generator that allows you to create simple logos in minutes.

​
6. Generate Custom Images with AI

You can also generate custom backgrounds and graphics using AI image tools. These tools can generate backgrounds, hero images, and visual elements for your app.

​
Step 1: Generate the image

Describe the style, mood, and layout you want. Example prompt: 
Soft sky background with floating food items like tacos, burgers, and drinks. Bright, playful, and colorful, 9:16 format.

​
Step 2: Upload the image to Woz

Copy or upload the image and paste it or attach it directly in the Woz chat and describe how it should be used. Example prompt: 
Use the uploaded image as the background for all screens in the app.
Or a more controlled version: 
Use the uploaded image as the background for onboarding and welcome screens. Apply a subtle overlay so text remains readable.

​
Step 3: Woz applies the design

Once the image is uploaded and the prompt is sent, Woz updates the app layout and applies the background image to the specified screens. You can refine the design further using Select Elements if needed. For example:
  • Adjust overlay opacity
  • Improve text contrast
  • Change button colors to match the background

Most of the time, a clear visual direction, a simple color palette, and thoughtful use of icons and images can dramatically improve how your app feels.Focus on clarity, consistency, and simplicity. With the right prompts and resources, Woz can help you create an app that looks polished and professional from the very first screen.
