One of the first decisions you'll face when building a mobile app is choosing the development approach. Should you build separate native apps for iOS and Android, or use a cross-platform framework? Let's break it down.

Understanding the Options

Native Development

Building separate apps using platform-specific languages:

iOS: Swift or Objective-C
Android: Kotlin or Java

Cross-Platform Development

Building one codebase that runs on both platforms:

React Native (JavaScript)
Flutter (Dart)
Xamarin (.NET)

Why We Recommend React Native

At Deep Gandhi, we primarily use React Native for cross-platform development. Here's why:

1. Cost Efficiency

One Codebase: 70-90% code sharing between iOS and Android
Faster Development: Build once, deploy twice
Lower Maintenance: Updates affect both platforms simultaneously

Example: Building native apps might cost $30,000-40,000 for both platforms, while React Native could cost $18,000-25,000.

2. Performance

Near-native performance for most use cases
Direct access to native APIs when needed
Smooth animations and interactions
Efficient rendering

3. Developer Ecosystem

Largest community among cross-platform frameworks
Backed by Facebook/Meta
Extensive libraries and components
Easy to find skilled developers

4. Time to Market

Launch on both platforms simultaneously
Faster iterations and updates
Quicker testing and debugging

When to Choose Native

Despite our preference for React Native, native development is better for:

1. Performance-Critical Apps

Heavy graphics (3D games)
Complex animations
Real-time processing
AR/VR applications

2. Platform-Specific Features

Deep iOS or Android integration
Using latest platform features immediately
Hardware-intensive applications

3. Large Enterprise Apps

Apps requiring maximum optimization
Long-term projects with dedicated teams
Budget not being a primary concern

The React Native Sweet Spot

React Native excels for:

Business Apps

ERP mobile clients
CRM applications
Inventory management
Order processing

E-Commerce Apps

Product catalogs
Shopping carts
Payment integration
User accounts

Social and Content Apps

News feeds
Messaging
Social networks
Content platforms

Service Apps

Booking systems
Delivery tracking
Customer portals
Service requests

Real Performance Comparison

Let's look at actual metrics from our projects:

Native App Performance:

Cold start: 0.8-1.2 seconds
Smooth 60 FPS animations
Instant navigation
100% platform consistency

React Native App Performance:

Cold start: 1.2-1.8 seconds
Smooth 60 FPS animations (with optimization)
Near-instant navigation
95% platform consistency

Verdict: For most business applications, the difference is negligible to end users.

Cost-Benefit Analysis

Example: E-Commerce App

Native Development:

iOS Developer: 3 months × $6,000 = $18,000
Android Developer: 3 months × $6,000 = $18,000
Total: $36,000
Timeline: 3 months (parallel development)

React Native Development:

React Native Developer: 2.5 months × $6,000 = $15,000
Platform-specific tweaks: $3,000
Total: $18,000
Timeline: 2.5 months

Savings: $18,000 (50%) and 2 weeks faster

Common Concerns Addressed

"Will it look native?"

Yes! React Native uses native components. iOS users see iOS UI elements, Android users see Material Design.

"What about app store approval?"

No issues. React Native apps are real native apps and follow all platform guidelines.

"Can we access native features?"

Yes! React Native has bridges to all native features. For custom needs, we can write native modules.

"What about updates?"

React Native supports over-the-air updates for JavaScript code, meaning faster bug fixes and feature updates.

Our Development Process

When building React Native apps, we follow this approach:

Architecture Planning
- Identify platform-specific requirements
- Plan for scalability
- Design data flow
Core Development
- Build shared codebase
- Implement business logic
- Create reusable components
Platform Optimization
- iOS-specific refinements
- Android-specific refinements
- Performance optimization
Testing
- Cross-platform testing
- Device-specific testing
- Performance testing
Deployment
- App Store submission
- Google Play submission
- CI/CD setup

Case Study: GMT24 Mobile App

Our recent project for GMT24 luxury watch marketplace:

Challenge: Build a mobile marketplace with:

Real-time inventory sync
Image-heavy product catalog
Push notifications
In-app messaging

Solution: React Native app with:

Optimized image loading
Efficient state management
Native module for camera access
Firebase for real-time features

Results:

Successfully deployed on both platforms
Excellent performance reviews
4.8★ rating on both stores
Cost 40% less than native approach

Making Your Decision

Choose React Native if:

✅ Budget is limited
✅ Need fast time-to-market
✅ Building standard business/consumer apps
✅ Want easier maintenance
✅ Need both iOS and Android

Choose Native if:

✅ Building performance-critical apps
✅ Need latest platform features immediately
✅ Have separate iOS and Android teams
✅ Budget is not a constraint
✅ Building complex games or AR/VR

The Bottom Line

For 80-90% of business applications, React Native is the smart choice. It delivers:

Native-quality user experience
Significant cost savings
Faster development and deployment
Easier maintenance and updates
