How to Embed Dynamic Forms in Your Mobile App (Like Google Forms, But Better)

Build beautiful, customizable forms for iOS and Android apps without releasing updates — the modern alternative to Google Forms and Typeform for mobile developers.

The Problem with Traditional Mobile Forms

If you've ever built a mobile app, you know the pain:

1. User signup needs an extra field? Push a new release.
2. Marketing wants to A/B test form layouts? Push a new release.
3. Need to change validation rules? Push a new release.

Meanwhile, web developers have enjoyed tools like Google Forms and Typeform for years — creating and updating forms instantly without touching code. But these tools weren't built for mobile apps, and embedding webviews creates a clunky, non-native experience.

What if you could build forms like Typeform, but render them natively in your mobile app, and update them instantly without app store reviews?

Enter Resync — a platform that brings the flexibility of web form builders to native mobile apps.

What is Resync?

Resync is a content management platform specifically designed for mobile apps. It includes a powerful visual editor where you build forms (and other UI components) that render natively in React Native applications. Think of it as:

• The power of Typeform's form builder ✨
• Combined with the flexibility of a headless CMS 📱
• Rendered as native mobile components 🚀

Why Resync for Mobile Forms?

1. Visual Form Builder (No Code Required)

Create forms using an intuitive drag-and-drop interface. Add text inputs, dropdowns, checkboxes, radio buttons, and more — all styled to match your app's design.

2. Native Performance

Unlike embedded webviews, Resync forms render as native React Native components:

• Smooth animations and interactions
• Consistent with iOS and Android design patterns
• Fast performance and small bundle size

3. Update Instantly

Change form fields, validation rules, or submit actions without releasing a new app version. Perfect for:

• Running experiments
• Seasonal campaigns
• Rapid iteration
• Emergency fixes

4. Advanced Features Out of the Box

• Comprehensive validation (email, URL, regex, min/max length, numeric ranges)
• Multiple submission methods (webhooks, custom functions, internal storage)
• Post-submission actions (navigation, alerts, deep links)
• Analytics integration (track form views, submissions, field interactions)
• Conditional logic (show/hide fields based on user input)

Getting Started in 5 Minutes

Step 1: Install the SDK

npm install resync-react-native
# or
yarn add resync-react-native

Install peer dependencies:

npm install react-native-svg lucide-react-native @react-native-async-storage/async-storage

Step 2: Initialize Resync

import Resync from 'resync-react-native';
import AsyncStorage from '@react-native-async-storage/async-storage';

// In your App.tsx or index file
Resync.init({
  key: 'your-api-key',
  appId: YOUR_APP_ID,
  callback: async () => {
    console.log('Resync initialized');
  },
  storage: AsyncStorage,
  environment: 'production',
});

Step 3: Render Your Form

import { ResyncContentView } from 'resync-react-native';

export default function SignupScreen() {
  return (
    <ResyncContentView
      name="UserSignupForm"
    />
  );
}

That's it! 🎉 You now have a fully functional form that you can edit from your dashboard without touching code.

Real-World Example: User Onboarding Form

Let's build a user onboarding form with email, name, and phone number fields.

In the Resync Dashboard:

1. Create a new Content Block called "OnboardingForm"
2. Add form elements:
   • Text input for "Full Name" (required, 2-50 characters)
   • Email input for "Email Address" (required, email validation)
   • Phone input for "Phone Number" (optional, tel format)
   • Checkbox for "Agree to Terms" (required)
   • Submit button
3. Configure submission:
   • Set submission type to "Webhook"
   • Add your API endpoint URL
   • Set success action to navigate to home screen

In Your React Native App:

import React from 'react';
import { SafeAreaView } from 'react-native';
import { ResyncContentView } from 'resync-react-native';
import { useNavigation } from '@react-navigation/native';

export default function OnboardingScreen() {
  const navigation = useNavigation();

  const navigationRegistry = {
    navigate: (routeName, params) => navigation.navigate(routeName, params),
    push: (routeName, params) => navigation.push(routeName, params),
    goBack: () => navigation.goBack(),
  };

  return (
    <SafeAreaView style={{ flex: 1 }}>
      <ResyncContentView
        name="OnboardingForm"
        navigationRegistry={navigationRegistry}
      />
    </SafeAreaView>
  );
}

What you get:

• ✅ Native form with proper keyboard types
• ✅ Client-side validation (email format, required fields)
• ✅ Automatic form submission to your API
• ✅ Success/error handling with navigation
• ✅ All configurable from your dashboard

Advanced Features

1. Custom Form Submission Logic

Submit forms to custom functions in your app:

const functionRegistry = {
  handleSignup: async (formData) => {
    // Your custom logic
    const { email, name, phone } = formData;
    
    try {
      await createUser({ email, name, phone });
      await analytics.track('user_signed_up');
      return { success: true };
    } catch (error) {
      console.error('Signup failed:', error);
      return { success: false, error: error.message };
    }
  },
};

<ResyncContentView
  name="OnboardingForm"
  functionRegistry={functionRegistry}
/>

Then in your dashboard, set the form submission type to "Function" and specify handleSignup as the function name.

2. Rich Validation Rules

Resync supports extensive validation out of the box:

• Required fields
• String validation: min/max length, regex patterns
• Number validation: min/max values, greater than, less than
• Format validation: email, URL, phone number
• Custom patterns: any regex for specialized validation

All configurable through the visual editor — no code changes needed.

3. Dynamic Forms with Remote Config

Change which form is displayed based on remote config:

import { useState, useEffect } from 'react';
import Resync, { ResyncContentView } from 'resync-react-native';

export default function DynamicFormScreen() {
  const [formName, setFormName] = useState('');

  useEffect(() => {
    // Get form name from remote config
    const configuredForm = Resync.getConfig('SIGNUP_FORM_VERSION');
    setFormName(configuredForm);
  }, []);

  return (
    <ResyncContentView name={formName} />
  );
}

Now you can A/B test different form designs, run seasonal campaigns, or show different forms to different user segments — all without app updates.

4. Analytics Integration

Track every interaction automatically:

import analytics from '@react-native-firebase/analytics';

const logAnalytics = (logId, event) => {
  analytics().logEvent(event.type, {
    logId,
    form_name: event.formName,
    field_name: event.fieldName,
    ...event.metadata,
  });
};

<ResyncContentView
  name="OnboardingForm"
  logAnalytics={logAnalytics}
/>

Resync automatically tracks:

• Form views
• Field interactions
• Validation errors
• Successful submissions
• Submission failures

5. Multi-Step Forms

Build complex multi-step forms using sections:

// Your dashboard form can have multiple sections
// - Section 1: Personal Info
// - Section 2: Company Details
// - Section 3: Preferences

// Each section can have its own validation and styling
// Navigate between sections with buttons configured in the dashboard

Submission Options

Resync supports three submission methods:

1. Webhook Submission

Submit form data to any API endpoint:

POST https://your-api.com/submit
Content-Type: application/json

{
  "name": "John Doe",
  "email": "john@example.com",
  "phone": "+1234567890"
}

2. Custom Function

Handle submissions with custom logic in your app (shown earlier)

3. Internal Storage

Store submissions in Resync's built-in database for later retrieval:

// Forms automatically save to Resync backend
// Retrieve submissions through the dashboard or API

FAQ

Q: Does Resync work with Expo?
A: Yes! Resync works with both Expo and bare React Native projects. Just follow the standard installation steps.

Q: What about iOS and Android differences?
A: Resync handles platform differences automatically. Forms adapt to platform-specific design patterns (iOS vs Material Design).

Q: Can I use Resync for more than just forms?
A: Absolutely! Resync is a complete content management system. Build:

• Marketing banners
• Feature announcements
• Onboarding flows
• Product catalogs
• Any dynamic UI content

Q: How does caching work?
A: Resync caches forms locally for instant loading. In development, caching is disabled. In production, cache expires after 6 hours (configurable).

Q: Is my data secure?
A: Yes. Resync uses industry-standard encryption for data in transit and at rest. Form submissions can be sent directly to your backend via webhooks, so sensitive data never touches Resync servers if you prefer.

Q: What if the Resync service is down?
A: Forms are cached locally after the first load. Your app continues working with the last cached version even if Resync is unreachable.
