Acceptable use: Don’t submit prompts that violate our Acceptable Use Policy. Prompts that are malicious, contain injections, or are too vague will be automatically rejected.

Creating mobile apps: Creating mobile apps with the AI App Generator is currently in beta and will initially be available to a small group of users. Access will expand gradually over time.

Bring your app idea to life with a well-written prompt. Here’s how to craft a clear, detailed prompt that helps Bubble AI build what you have in mind. These guidelines apply whether you’re building a web app or a .

What to include

  • App type and purpose – What kind of app is it, and what problem does it solve?

  • Target users – Who is this app for?

  • Core features – What should users be able to do?

  • Visual style – Any colors, mood, or design references to guide the look and feel

Example structure

"A [app type] for [target users] to [main purpose]. Users can [key features]. Style should be [visual preferences]."

Effective Prompt Examples

✅ Good Examples

Task Management App

A productivity app for small teams to track project tasks and deadlines. Team members can create tasks, assign them to colleagues, set due dates, and mark completion. Clean, minimalist design with blue and white colors.

Local Restaurant Finder

A discovery app for food lovers to find nearby restaurants and read reviews. Users can search by cuisine type, view restaurant details, see ratings, and save favorites. Modern design with warm colors and food photography.

Fitness tracker

A wellness app for fitness enthusiasts to log workouts and track progress. Users can record exercises, set goals, view workout history, and share achievements. Energetic design with bright green accents and dark mode support.

✅ Tips for better results

1

Be specific about purpose

Instead of: "A business app" Try: "An invoice management app for freelancers"

2

Define your users clearly

Instead of: "For everyone" Try: "For college students planning events"

3

Give visual directions

Instead of: "Make it look good" Try: "Professional design with navy blue and gold, inspired by financial apps"

4

Focus on core features first

Instead of: "Users can do everything they need" Try: "Users can create events, invite friends, and track RSVPs"

❌ What to avoid

1

Being too vague

"Make me a social app that's really cool and modern."

2

Too detailed on layout

"Put the login button in the top right corner, make the sidebar exactly 250px wide, and use Helvetica font for all headers."

3

Technical specifications

"Integrate with Stripe API, use PostgreSQL database, and implement OAuth authentication with Google and Facebook."

Style and design guidelines

There is some overlap between color and mood, but make sure you include both in your prompt.

Color Preferences

  • Be specific: "forest green and cream" vs. "green"

  • Mention themes: "dark mode," "minimalist," "vibrant"

  • Reference styles: "corporate professional," "playful startup"

Mood and feel

  • Professional and corporate

  • Fun and playful

  • Clean and minimalist

  • Bold and modern

  • Warm and friendly

Limitations with generating a mobile app

When generating a mobile app using the AI app generator, there are a few important limitations to be aware of.

The generator creates UI layouts, dynamic expressions, and data types, but it does not generate workflows or sample data. Instead, it includes canvas placeholders so that dynamic expressions are correctly connected. However, because there’s no sample data, you’ll need to add some yourself to see how the app functions in run mode.

If your app appears blank in preview mode but looks populated in the design tab, this is expected — it’s caused by the canvas placeholders being present without data. Once you add sample data, the app will display as intended.

FAQ

What is sample data?

The AI App Generator currently doesn't create sample data for mobile apps. To see how the app functions in run mode, you'll need to add sample data yourself.

Sample data refers to placeholder information that mimics real data and is used during the app-building process. Bubble AI generates sample data to help you visualize how your app will look and function once it’s populated with actual user information. For example, if your app includes a list of users or a gallery of products, Bubble AI might fill those areas with sample names or descriptions.

This temporary data is particularly useful for making sure your app works: testing and refining the design, workflows, and overall user experience before launching your app. Once you’re satisfied with the app’s structure, you can replace the sample data with live information or accept real data coming from your users. By including realistic sample data, Bubble ensures you can clearly see how your app will behave in a real-world scenario.

Why does my mobile app look empty in run mode?

The AI App Generator currently doesn’t create sample data for mobile apps. It adds canvas placeholders so dynamic expressions are correctly connected, but you’ll need to add your own data to see how the app behaves in run mode.
