Question 1

What is React Native and how does it work?

Accepted Answer

React Native is a cross-platform mobile development framework created by Meta (Facebook). It allows developers to build native iOS and Android applications using JavaScript and React. The framework renders native UI components, not web views, resulting in performance nearly identical to native apps.

Question 2

How much cheaper is React Native vs native development?

Accepted Answer

React Native development typically costs 40-60% less than building separate native iOS and Android apps. For a $200,000 native project (both platforms), you could build the same app in React Native for $80,000-$120,000, saving $80,000-$120,000.

Question 3

Is React Native as good as native apps?

Accepted Answer

For 95% of use cases, yes. React Native apps achieve near-native performance and are indistinguishable from native apps to users. Facebook, Instagram, and Airbnb all use React Native. For graphically intensive games or apps requiring cutting-edge platform features, native may be better.

Question 4

What apps are built with React Native?

Accepted Answer

Major apps built with React Native include Facebook, Instagram, Airbnb, Tesla, Walmart, Bloomberg, Shopify, Discord, Pinterest, and Uber Eats. These apps serve hundreds of millions of users with excellent performance.

Question 5

Can React Native access device features like camera and GPS?

Accepted Answer

Yes! React Native has excellent access to device features through its native bridge. Camera, GPS, Bluetooth, push notifications, biometrics, and most native features work seamlessly. For newer features, we can write custom native modules.

Question 6

Is React Native good for startups?

Accepted Answer

React Native is ideal for startups. It reduces costs by 50%, speeds time-to-market, and allows you to launch on both platforms simultaneously with one team. This is why it's the framework of choice for most VC-backed startups.

Question 7

Can you convert existing apps to React Native?

Accepted Answer

Yes, we offer migration services. We can gradually migrate your existing iOS or Android app to React Native, maintaining functionality while reducing future maintenance costs. This is called the 'brownfield' approach.

Question 8

How long does React Native development take?

Accepted Answer

React Native development is typically 40% faster than native development. An MVP takes 3-4 months, a full app 4-6 months, and enterprise apps 6-9 months. Hot reloading accelerates iteration by 3x compared to native.

Question 9

Can we add native code to React Native?

Accepted Answer

Absolutely! React Native supports native modules, allowing you to write Swift/Objective-C (iOS) or Kotlin/Java (Android) code when needed. This gives you the best of both worlds - cross-platform efficiency with native capabilities.

Question 10

Is React Native dying?

Accepted Answer

No! React Native is actively maintained by Meta with regular releases. It has a massive community, is used by Facebook and Instagram daily, and Meta recently released the New Architecture improving performance significantly. It's more alive than ever.

Question 11

What's the difference between Expo and Bare workflow?

Accepted Answer

Expo is a managed workflow that simplifies development with pre-built features and easier setup. Bare workflow gives more control and access to native code. We typically start with Expo and eject to bare if advanced native features are needed.

Question 12

Can React Native integrate with existing native code?

Accepted Answer

Yes! React Native can be integrated into existing native iOS or Android apps. You can add React Native screens to your existing app incrementally, which is great for companies wanting to gradually adopt cross-platform development.

Question 13

Do you provide React Native maintenance?

Accepted Answer

Yes, we offer ongoing maintenance packages. The advantage of React Native is that one update applies to both platforms, reducing maintenance costs by 50% compared to maintaining separate native apps.

Question 14

React Native vs Flutter - which is better?

Accepted Answer

Both are excellent. React Native has a larger ecosystem, uses JavaScript (more developers available), and is battle-tested by Facebook. Flutter offers slightly better performance for complex animations. We recommend React Native for most projects due to ecosystem maturity.

Question 15

What's the cost of React Native app maintenance?

Accepted Answer

React Native maintenance costs 50% less than native because updates are applied once to both platforms. Monthly maintenance packages typically range from $2,000-$10,000 depending on app complexity and update frequency.
