Mobile Development
There are 7 billion smartphones in the world. That's 7 billion computers in people's pockets, running your code, talking to your servers, storing their data. Mobile isn't just a platform—it's the platform.
Mobile development is its own discipline with unique constraints: limited battery, unreliable networks, strict platform gatekeepers, and users who will uninstall your app if it crashes once. The good news? The tooling has never been better.
TL;DR
- Native (Swift/Kotlin) for maximum performance and platform polish
- Cross-platform (React Native/Flutter) for faster iteration and code sharing
- Mobile-first thinking: offline-first, battery-aware, network-efficient
- Plan for app store reviews, updates, and the entire release lifecycle
The Big Decision: Native vs. Cross-Platform
This is the first choice you'll make, and it shapes everything that follows.
When to Go Native
- Performance-critical apps (games, video, AR/VR)
- Apps that need deep platform integration
- When you have dedicated iOS and Android teams
- When you're building for just one platform
When to Go Cross-Platform
- Content-driven apps (news, social, e-commerce)
- Startups that need to ship fast
- Teams with web development experience
- When you need feature parity across platforms

Mobile-Specific Challenges
Mobile development isn't web development with a smaller screen. You're dealing with real constraints:
Platform Integration
Mobile apps can access capabilities web apps can't:
- Push notifications
- Deep linking
- In-app purchases
- Camera, GPS, and sensors
- Biometric authentication
- Widgets and extensions
The App Store Gauntlet
Unlike web apps, you can't just push a fix. Updates go through review.
Learning Path
Beginner
Pick one platform (iOS or Android) or one framework (React Native or Flutter). Build something simple. Get it on a real device.
Intermediate
Master state management, navigation, and network requests. Handle edge cases (offline, errors). Ship to a test group.
Advanced
Deep platform integration (widgets, background tasks). CI/CD for mobile. Performance optimization. App Store optimization.
