How long does it take to learn to program?

The time it takes you to learn to program depends on various factors. Each learner has different requirements, and the time you invest plays a decisive role. However, there are no fixed guidelines as to how long it takes to learn to program. You can learn some basic skills in just a few months, while developing advanced apps with more complex features can take more time. However, it is a continuous process of learning and practice that pays off over time.

Requirements: What do I need to program an app?

Before you can develop your own app, you need some basic skills and requirements:

Basic skills:

• Logical thinking: An essential part of computer science for identifying problems and developing efficient solutions.
• problem-solving mentality: The ability to overcome challenges and find pragmatic solutions.
• Basic understanding of programming concepts: Knowledge of basic programming principles such as variables, loops, conditions, and functions.

Technical requirements:

• A computer with suitable software: Installed development environments such as Xcode (for iOS) or Android Studio (for Android).
• Internet access: For research, online resources, and access to tutorials that support the learning process.

Optional knowledge:

• Familiarity with UI/UX principles: Basic skills in designing user-friendly apps to ensure an appealing and intuitive user experience.

Best programming languages for iOS and Android apps

The best programming language for apps often depends on which platform you're targeting. Here are some of the most popular programming languages and App development frameworksthat are used in app development:

• Swift: This programming language has been developed specifically for the development of iOS apps (iPhone, iPad). Swift is easy to learn, powerful, and performs well. It's the best choice if you want to focus on iOS apps. Apple has continuously improved Swift, making it one of the most popular programming languages for mobile applications.
• Java/Kotlin: Java and Kotlin are the two dominant programming languages for developing Android apps. Java is one of the oldest and most widely used programming languages, while Kotlin is considered a modern alternative that offers many benefits, including shorter syntax and better integration with Android Studio. Kotlin is preferred by Google and has quickly established itself as the better choice for many developers.
• JavaScript/Dart: If you're interested in cross-platform development, where you can build apps for both iOS and Android, JavaScript and Dart offer excellent options with the React Native and Flutter frameworks. Both frameworks allow you to build an app with a single code base for both platforms, saving time and money. React Native is based on JavaScript, making it ideal for developers who are already familiar with web technologies. Flutter uses Dart and offers very good performance and an attractive design.

Develop your own app for beginners: recommendations

• If you want to develop iOS apps, Swift is the best choice because it's specifically designed for the Apple platform and offers excellent documentation and resources.
• If you want to focus on Android apps, Kotlin is recommended as it's modern, powerful, and officially supported by Google.
• If you want to work cross-platform to cover both Android and iOS, then you should consider Flutter (Dart) or React Native (JavaScript). Both offer good support and large developer communities, making it much easier to get started.

The choice of programming language therefore depends largely on which platform you are aiming for and how much flexibility you want to have during development.

App Development: A Step-by-Step Process

Developing an app can be a complex task, but when you break the process down into clear steps, it becomes much more manageable. Here is a detailed overview of the individual phases of app development:

1. Develop an idea:

• Identify a problem or develop a unique app concept: Think about which problem you want to solve with your app or which new, creative idea you can implement. A good app is based on a clear goal.
• Research the target group: Find out who your potential users are and what they expect from an app. What are their needs or wishes? This helps you build an app that really adds value.

2. Create a concept:

• Define features and functions: Outline the core features you want your app to have. What options should it offer users? Also consider which platforms you want to support (iOS, Android, or both).
• Create wireframes or prototypes: Visualize your app idea through wireframes or interactive prototypes. This helps you plan the user interface (UI) and user experience (UX) before you start programming.

3. Choose the right platform:

• Native development (iOS/Android): Decide whether you want to develop a native Android or iOS app or a web app for both platforms. If you're developing an app for a single platform, you should choose native development. Use Swift for iOS, Java or Kotlin for Android. Native apps offer the best performance and user experience, as they are specifically optimized for each platform. Here is the difference between Native vs Cross Platform to bear: While native apps offer tailor-made solutions for every platform, cross-platform frameworks focus on a common code base for both platforms.
• Cross-platform frameworks: If you want to develop an app for both platforms, frameworks like Flutter or React Native are a good choice. These make it possible to create a single code base that runs on both iOS and Android.
• App builders for simpler apps: If you don't have deep programming skills or want to build a simple app, you can use tools like Open as App or Appgyver. These app builders allow you to create apps without much programming.

4. Program the app:

• Write code for core features: Now it's time to write the actual code. This includes implementing the basic features and building the user interface.
• Implement backend services: If your app requires features such as databases, user authentication, or cloud storage, you'll also need to set up the backend. Technologies such as Firebase or AWS can be helpful here.

5. Test and debug:

• Identify and fix bugs: Testing is a crucial step. It's important to find and fix any bugs in the app before you publish them. This can be done through manual testing or automated testing.
• Use testing tools: You can use emulators or real devices to test the app under various conditions and make sure it runs stably across all platforms.

6. Publish app:

• Guidelines for publishing in app stores: Each app store, such as the Google Play Store or the App Store, has specific publishing requirements. This includes design guidelines, privacy statements, and more. Make sure that your app meets these requirements before you upload it.
• Beta testing for user feedback: Before final release, do a beta test to get feedback from real users. This helps identify potential issues and improve the app before it is widely released.

7. Maintenance and updates:

• Continuous improvements based on user feedback: After the app is released, it's important to regularly respond to user feedback and add new features or improvements.
• App updates for operating system changes: Operating system updates (such as new iOS or Android versions) also often require adjustments to your app, so make sure to keep your app up to date to ensure smooth use.

Create an app without programming knowledge

Not everyone who wants to build an app has deep programming skills. Fortunately, there are various app kits that also enable beginners to develop a working app without code. Here are some of the most popular tools that offer easy app development:

• Appgyver: Appgyver is a platform that allows users to create apps for iOS and Android without programming knowledge. With a drag-and-drop interface, users can assemble complex apps with visual building blocks. It offers many ready-made features that simplify the development process.
• Open as App: Open as App is a platform that makes it possible to transform data (e.g. Excel spreadsheets or Google Sheets) into fully functional apps. It is particularly suitable for simple applications that are heavily data-driven. Again, no programming is required and the user interface is easy to customize.
• Thunkable: Thunkable is another easy-to-use tool that makes it possible to develop apps without programming knowledge. It offers a drag-and-drop interface and the ability to build apps for iOS and Android at the same time. Thunkable offers a wide range of features to build interactive and dynamic apps.

Advantages and disadvantages of app kits compared to manual programming:

advantages:

• Easy to use: The biggest advantages of app builders are their ease of use and the quick learning curve. You can start developing your app right away without any previous knowledge.
• Quick results: With visual tools, you can create a working app within a short period of time, which in most cases is already user-friendly and functional.
• Lower costs: You can develop an app without having to involve a developer or expensive development resources. This makes app builders particularly attractive for small companies or individuals with limited budgets.

Disadvantages:

• Limited customization options: App builders offer only limited customization options. If you need a particularly complex or tailor-made app, these tools will quickly push you to your limits.
• Less control: Since you don't have direct access to the code, it's harder to make profound changes or optimizations. The performance of the app can also sometimes lag behind a natively programmed app.
• scalability: If your app grows over time and needs additional features, it can be difficult to further expand the app with a modular tool. For complex apps with many functions, manual programming is usually the better choice.

How long does it take to learn to program?

The time it takes you to learn to program depends on various factors. Each learner has different requirements, and the time you invest plays a decisive role. Here are some of the key factors that influence learning time:

Factors that influence learning time:

• Previous programming experience: If you already have basic programming skills or are familiar with other technical disciplines, you'll learn faster than someone who starts from scratch. Previous knowledge of logic or mathematics can also be an advantage.
• Time you dedicate to learning: The more time you spend studying regularly, the faster you'll make progress. It is not only important to learn a lot, but also to practice regularly to consolidate what you have learned.

Learning progress estimates:

• Basic understanding (1-2 months): If you focus on the basics of programming, such as understanding variables, loops, and functions, you can get a good basic understanding in around 1 to 2 months. During this time, you will be able to write simple programs and develop initial app ideas.
• Advanced app programming (6—12 months): It usually takes 6 to 12 months to master advanced app development — including developing complex apps, implementing backend services, and using frameworks such as Flutter or React Native. This requires continuous learning and intensive practice.

Recommendations for consistent study habits and practice:

• Daily exercise: Even if you only invest 30 minutes to 1 hour per day, daily practice can make a big difference. It is better to study short units regularly than sporadically longer periods of time.
• Implement projects: One effective way to deepen what you've learned is to create small projects. Start with simple apps or programs to get hands-on experience.
• Use resources: Use online courses, tutorials, books, and forums. There are plenty of free and paid resources to help you structure your learning journey.
• See mistakes as a learning opportunity: Errors will often occur during programming. They are part of the learning process. It is important to use this as an opportunity to improve and to remain patient.

Programming apps: tips for beginners

Getting started with app development can feel overwhelming, but with the right strategies, you can significantly simplify the learning process. Here are some valuable tips that will help you get off to a successful start as a beginner:

• Start with small, manageable projects: Instead of starting a complex project right away, start with simple apps or programs that you can complete in a short time. Small projects help you understand basic concepts and quickly give you a sense of success that increases your motivation.
• Focus on learning one programming language at a time: It can be tempting to learn multiple programming languages at the same time, but that can lead to confusion. Pick a language (such as Swift for iOS or Kotlin for Android) and focus on mastering it well before moving on to another. A solid foundation in one language makes the transition to others easier later on.
• Practice debugging skills early: Finding and fixing errors (bugs) is an important part of programming. Start developing your debugging skills early on. Learn to read errors and use tools such as debuggers and consoles to identify issues. The sooner you develop these skills, the easier it will be for you to develop complex apps later on.
• Use open-source projects for inspiration and guidance: There are lots of open-source projects on platforms like GitHub that you can look at to learn how experienced developers write code. Not only can you use these projects as a source of inspiration, but you can also actively participate in them to improve your skills. Studying other developers' code is one of the best ways to learn best practices and avoid mistakes.
