Native vs Cross-Platform App Development: Which Should You Choose?

One of the first technical decisions in an app project is how to build it: natively for each platform, or once with a cross-platform framework that runs on both iOS and Android. Both approaches produce real apps in the App Store and Google Play. The difference is in cost, performance and how much each platform's specific features matter to you.

Native development

Native apps are built separately for each platform using its own languages and tools: Swift for iOS and Kotlin for Android. Strengths

• The best possible performance and smoothness.
• Immediate access to every device feature and new operating system capability.
• An interface that feels completely at home on each platform.

Trade-offs

• Two codebases to build, test and maintain, which usually means a higher cost.
• Features can drift apart between the iOS and Android versions.

Cross-platform development

Cross-platform frameworks such as Flutter and React Native let developers write most of the app once and run it on both iOS and Android. Strengths

• One main codebase, which usually means lower cost and faster delivery.
• The same features ship on both platforms at the same time.
• Easier long-term maintenance.

Trade-offs

• Some advanced device features need extra native code.
• Very graphics-heavy apps, such as complex games, may perform better natively.

Web apps and progressive web apps

A third option is a web app that runs in the browser. Progressive web apps (PWAs) can be added to the home screen and work with limited connectivity. They're the cheapest way to reach every device and don't need app store approval, but they have less access to device features, and app store distribution is limited.

How to choose

Choose cross-platform if:

• You need iOS and Android on a limited budget.
• Your app is mostly forms, content, lists, bookings or e-commerce.
• You want one team maintaining one codebase.

Choose native if:

• Performance is critical, for example real-time graphics, audio or video processing.
• The app depends heavily on the latest platform features.
• You're building for one platform only.

Choose a web app if:

• You want to test an idea quickly and cheaply.
• Users will mostly use it on desktop, or occasionally.

What this means for cost

The approach is one of the biggest factors in your app budget. Read our guide to app development costs in South Africa, and our comparison of websites and apps if you're still deciding what to build.

Our approach

We recommend the approach based on your features, users and budget, not on a favourite technology. See our mobile app development service or contact us to discuss your app.
