App Development Basics
What is an app?
An app, or application, is a software product designed to run on mobile devices such as smartphones and tablets. Apps can range from simple tools to complex systems for banking or social media. The use of apps has increased greatly in recent years, which underscores the importance of a presence in the app market.
Different types of app development
There are mainly three approaches to creating an app:
- Native app development: Apps are built specifically for one platform (iOS or Android) using platform-specific programming languages and tools.
- Cross-platform development: Using frameworks such as Flutter or React Native, developers can write one codebase that runs on multiple platforms, often reducing both development time and cost.
- Web-apps: Apps that run in browsers and are optimized for mobile devices are commonly referred to as progressive web apps (PWA).
Why is the choice of platform important?
The choice of development platform affects, among other things:
- Development costs and time
- App performance and user experience
- Maintenance requirements
- Access to platform-specific features
- Competency requirements for the development team
In a market where efficiency and quality are highly valued, choosing the right platform can be critical to a project's success.
Flutter: Google's framework for cross-platform development
Flutter is an open-source UI framework that allows developers to build native-like apps for mobile, web, and desktop from a single codebase.
What is Flutter?
Flutter uses the Dart programming language and offers a set of pre-built widgets. Instead of utilizing native UI components, Flutter draws all user interface elements with its own rendering engine. This gives developers complete control over the look and experience.
Benefits of Flutter
- Fast development with features like Hot Reload.
- Consistent user experience across platforms.
- Near native performance through compilation to native code.
- One codebase reduces maintenance costs.
- Support for both web and desktop provides opportunities for extended platform coverage.
Disadvantages of Flutter
- The ecosystem is somewhat young compared to native development.
- Apps can have somewhat larger file size.
- Some advanced features may require additional work with native code.
- Developers have to learn Dart, which is less widely used than other languages.
React Native: Facebook's solution for cross-platform development
React Native allows developers to build mobile apps with JavaScript and React, and utilizes native UI components to create authentic user experiences.
What is React Native?
React Native combines JavaScript with native components. The code communicates with a platform-specific “bridge” to render the user interface, allowing developers to reuse much of their web expertise in mobile development.
Benefits of React Native
- A large developer community with widely experienced JavaScript developers.
- Fast iteration with Hot Reloading.
- Sharing codebase for iOS and Android.
- Mature ecosystem with a wide variety of libraries and tools.
Disadvantages of React Native
- Somewhat lower performance than native solutions, especially for complex apps.
- The “bridge” between JavaScript and native components can lead to bottlenecks.
- Updates and version changes may require additional work.
- Variations in the quality of third-party libraries.
- Less control over detailed pixel-perfect design.
Native App Development: Platform-Specific Approach
Native app development involves developing apps for each platform using respective programming languages and tools.
What is Native App Development?
For iOS, apps are developed using Swift or Objective-C, while Android uses Kotlin or Java. This approach provides full access to all of the platform's features and optimal performance.
Benefits of Native Development
- Best performance and responsiveness.
- Direct access to all device APIs and features.
- The user interface follows platform-specific design guidelines, providing an intuitive experience.
- Early support for new features from the platform providers.
- Effective debugging and testing with tools provided by the platform.
- High security with native tools and mechanisms.
Disadvantages of Native Development
- Higher development costs due to separate code bases for each platform.
- Longer development time to implement the same functionality across platforms.
- Increased maintenance costs with separate updates for each platform.
- Requires developers with specific platform expertise, which can be challenging to recruit.

Decision Criteria: How to Choose the Right Platform for Your App
The choice between Flutter, React Native and native development depends on several factors:
- Project complexity and requirements:
- Simpler apps can often be built with cross-platform solutions, while apps with high performance requirements and advanced functionality can benefit from native development.
- Budget and Timeframe:
- Cross-platform options can provide faster time-to-market and lower costs, while native development often requires greater investment in both time and resources.
- Target Platforms:
- If you want to support both iOS and Android, cross-platform development provides an easier solution, while a one-sided focus can make native development more appropriate.
- Team Competence:
- If your team is familiar with JavaScript and React, React Native may be a natural choice. If, on the other hand, you want to leverage specialized mobile development expertise, native development or Flutter may be appropriate options.
- Long-term maintenance:
- A common codebase for multiple platforms can simplify maintenance, while separate codebases require dedicated teams for each platform.
Future perspectives: Where is app development going?
The app development landscape is constantly changing:
- Flutter:
- The platform is developing rapidly and gaining ever wider support. It is designed to be able to be extended to more platforms in the future.
- React Native:
- With a mature technology base and a large developer community, React Native remains a popular choice for many.
- Native development:
- Improvements in development tools make native development more efficient, and new frameworks help reduce some of the complexity.
- Hybrid approaches:
- Many people choose a combination of native and cross-platform development to balance performance and development efficiency.
Conclusion: Which platform is best for your business?
The choice between Flutter, React Native and native development depends on the goals, requirements and resources of the project.
- Flutter can be ideal if you want a quick and cost-effective solution for multiple platforms with a modern technology.
- React Native is a good choice if your team has strong JavaScript expertise and you want a balanced solution with broad support.
- Native development is best suited when performance, security and optimal user experience are paramount, despite higher costs and longer development time.
Whichever platform you choose, it is important to have a clear understanding of the project's goals and requirements before starting the development process.
App Development FAQs
How do you create an app from scratch?
Start by defining the purpose and target audience of the app, create a prototype, select the development platform and build the app. Test thoroughly before launch. The process requires both technical expertise and a deep understanding of user experience.
How much does it cost to develop an app?
Development costs vary based on the complexity, design, and functionality of the app. In general, a simpler app will be less expensive, while more complex solutions with advanced features require greater investment. It is important to consider both development costs and long-term maintenance costs.
How long does it take to develop an app?
Development time depends on the complexity of the app. Smaller apps can often be developed faster, while larger and more complex applications take longer. Many projects start with a minimum functional version (MVP) to test the market before full-scale development is set in motion.
Can I convert my website into an app?
Yes, there are several approaches to converting a web page into an app. You can develop a progressive web app (PWA) or use a hybrid framework to integrate website functionality into an app.
