Replay: Convert Video to a Production-Ready React Native App in Under 60 Minutes (2026)

TL;DR: Replay transforms video recordings of user interactions into production-ready React Native applications, understanding user intent and generating complete, functional code in under an hour.

The future of mobile app development is here, and it's powered by video. Stop manually translating design mockups and user stories into code. Start leveraging the power of video to reconstruct fully functional React Native applications with Replay.

The Problem: From Idea to App is Too Damn Long#

Building mobile apps is a complex and time-consuming process. Traditional methods involve:

• •Static design tools (Figma, Sketch) that require manual translation to code.
• •Lengthy development cycles with constant iterations and bug fixes.
• •Difficulty capturing the intent behind user interactions. You see the UI, but not why the user tapped that button.

Screenshot-to-code tools offer a marginal improvement, but they only capture a snapshot of the UI, not the dynamic behavior. This leads to incomplete and often buggy code that requires significant manual intervention.

Replay: The Video-to-Code Revolution#

Replay changes the game by analyzing video recordings of user interactions. Instead of static images, Replay's "Behavior-Driven Reconstruction" engine, powered by Gemini, understands the flow of the application, the intent behind each action, and generates complete, production-ready React Native code.

This isn't just about recreating the UI; it's about reconstructing the experience.

How Replay Works: From Video to Working App#

Replay uses a multi-stage process to convert video into code:

1. •Video Analysis: Replay analyzes the video frame by frame, identifying UI elements, user actions (taps, swipes, text input), and transitions between screens.
2. •Behavior Understanding: Replay's AI engine infers the user's intent behind each action, understanding the underlying logic and data flow.
3. •Code Generation: Replay generates clean, well-structured React Native code, including UI components, navigation logic, data bindings, and event handlers.
4. •Integration & Customization: Replay allows you to integrate with backend services (like Supabase), inject custom styles, and customize the generated code to meet your specific needs.

Key Features That Set Replay Apart#

• •Multi-Page Generation: Replay handles complex, multi-page applications with ease, automatically generating navigation and data flow between screens.
• •Supabase Integration: Seamlessly integrate your React Native app with Supabase for backend services, including authentication, data storage, and real-time updates.
• •Style Injection: Customize the look and feel of your app with custom CSS or styled components.
• •Product Flow Maps: Visualize the user flow within your application, making it easier to understand and optimize the user experience.

Replay vs. The Competition: A Clear Winner#

Building a React Native App with Replay: A Step-by-Step Guide (Under 60 Minutes)#

Let's walk through the process of converting a video recording into a functional React Native application using Replay. We'll assume you have a video of a user interacting with a mobile app prototype.

Step 1: Upload Your Video to Replay#

1. •Create an account on Replay.
2. •Click the "Upload Video" button and select your video file.
3. •Replay will automatically begin analyzing the video. This process may take a few minutes, depending on the length and complexity of the video.

💡 Pro Tip: Ensure your video is clear and well-lit for optimal analysis. A stable recording is crucial.

Step 2: Review and Refine the Generated Code#

Once the analysis is complete, Replay will present you with the generated React Native code.

1. •Browse through the code, examining the generated components, screens, and navigation logic.
2. •Use Replay's visual editor to make minor adjustments to the UI or layout.
3. •Identify any areas where Replay may have misinterpreted the user's intent and correct the code accordingly.

Step 3: Integrate with Supabase (Optional)#

If your app requires backend services, you can easily integrate with Supabase.

1. •Create a Supabase project and obtain your API keys.
2. •In Replay, navigate to the "Integrations" tab and connect to your Supabase project.
3. •Replay will automatically generate the necessary code to interact with your Supabase database and authentication services.

typescript
// Example: Fetching data from Supabase
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_ANON_KEY';
const supabase = createClient(supabaseUrl, supabaseKey);

const fetchData = async () => {
  const { data, error } = await supabase
    .from('your_table')
    .select('*');

  if (error) {
    console.error('Error fetching data:', error);
    return [];
  }

  return data;
};

export default fetchData;

Step 4: Style Your App#

Customize the look and feel of your app by injecting custom styles.

1. •Use Replay's style editor to add CSS or styled components to your React Native components.
2. •Apply your brand colors, fonts, and design elements to create a unique and visually appealing app.

javascript
// Example: Styled Component
import styled from 'styled-components/native';

export const Container = styled.View`
  flex: 1;
  background-color: #f0f0f0;
  align-items: center;
  justify-content: center;
`;

export const Title = styled.Text`
  font-size: 24px;
  font-weight: bold;
  color: #333;
`;

Step 5: Deploy Your App#

Once you're satisfied with the generated code and styling, you can deploy your app to the app stores.

1. •Download the generated React Native project from Replay.
2. •Use your preferred build and deployment tools (e.g., Expo, React Native CLI) to build and deploy your app to the iOS App Store and Google Play Store.

📝 Note: Ensure you have the necessary developer accounts and certificates for app store deployment.

Benefits of Using Replay#

• •Faster Development: Significantly reduce development time by automating the code generation process.
• •Improved Accuracy: Capture the intent behind user interactions, leading to more accurate and functional code.
• •Reduced Costs: Lower development costs by reducing the need for manual coding and debugging.
• •Enhanced Collaboration: Facilitate collaboration between designers and developers by providing a common language (video).
• •Rapid Prototyping: Quickly create and iterate on mobile app prototypes.

The Future is Video-Driven#

Replay represents a paradigm shift in mobile app development. By leveraging the power of video and AI, we can dramatically accelerate the development process, improve the quality of our code, and ultimately create better user experiences.

⚠️ Warning: While Replay automates much of the development process, it's crucial to have a solid understanding of React Native and mobile app development principles to effectively use and customize the generated code.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features and usage. Paid plans are available for more advanced features and higher usage limits. Check the Replay pricing page for the latest details.

How is Replay different from v0.dev?#

While both tools aim to accelerate UI development, Replay focuses on video analysis and behavior-driven reconstruction, understanding the intent behind user interactions. v0.dev primarily uses text prompts and AI to generate UI components, but it lacks the ability to analyze and interpret real-world user behavior captured in video. Replay offers a more complete and accurate solution for building functional applications.

What if Replay misinterprets the video?#

Replay provides a visual editor that allows you to easily correct any misinterpretations and fine-tune the generated code. The more you use Replay, the better it becomes at understanding your design patterns and coding preferences.

What types of videos work best with Replay?#

Clear, well-lit videos with stable camera angles work best. Avoid videos with excessive noise or distractions. Focus on capturing the key user interactions and flows within your app prototype.
