First, understand the options
Mobile apps are built in a few different ways. You do not need to learn all of them. Pick one path, build real apps with it, and you can learn another later.
- Native Android: apps built with Kotlin (and the older Java) using Android Studio. Google's recommended modern UI toolkit is Jetpack Compose.
- Native iOS: apps built with Swift and SwiftUI using Xcode. Xcode runs only on a Mac, so this path needs Apple hardware.
- Cross-platform with Flutter: one codebase in the Dart language that runs on Android and iOS (and more).
- Cross-platform with React Native: one codebase in JavaScript or TypeScript, using React ideas. A natural next step if you already know React for the web.
Which path should a beginner choose?
- If you have a Windows or Linux laptop and an Android phone, start with Android (Kotlin) or a cross-platform option. iOS development needs a Mac.
- If you already know JavaScript and React, React Native will feel familiar.
- If you want one codebase for both platforms and are starting fresh, Flutter is a popular choice.
- Whatever you pick, the fundamentals are the same: programming logic, UI layout, state, navigation, data from APIs and local storage.
What you need
- A laptop or desktop. Mobile development tools such as Android Studio and phone emulators need a fair amount of memory; 8 GB RAM is a practical minimum and more is better. Check the current system requirements on the official site.
- An Android phone for testing is very useful (emulators work, but a real device is faster on low-memory laptops).
- Free tools: Android Studio, VS Code, Git, and the SDK for your chosen path.
- Publishing to the app stores needs a developer account. Google Play charges a one-time registration fee and Apple charges a yearly fee — check the current amounts on their official sites. You can learn and test for free without publishing.
What to learn, in what order
- Programming fundamentals. Variables, conditions, loops, functions, lists and objects in any one language. Python or JavaScript are friendly first languages; the logic carries over to Kotlin, Dart or Swift.
- Git and GitHub. Keep every app in a repository from the first day. Learn commits, branches and pull requests.
- How apps talk to servers. HTTP, APIs and JSON. Most real apps load data from a back end, so understanding this early saves confusion later. Building a small website first is a good way to learn it.
- Your app language. Kotlin for Android, Dart for Flutter, JavaScript/TypeScript for React Native, or Swift for iOS.
- Layouts and UI components. Text, buttons, images, lists, input fields, and arranging them on different screen sizes. Learn the basics of good, accessible design.
- State and navigation. How the screen updates when data changes, and how to move between screens. This is the heart of every app.
- Data from APIs and local storage. Load data from a public API, show loading and error states, and save data on the device so the app works offline.
- A simple back end. Build your own API (for example with Django or Node.js) with login and a database, so your app can store user data.
- Testing, release and updates. Test on real devices, fix crashes, build a release version, and learn how app store review and updates work.
Projects to build
- A tip or marks calculator (layouts, input, state).
- A to-do list that saves on the device (local storage).
- A news, weather or recipe app using a public API.
- An app with login connected to your own back end.
- A team project with a friend, using pull requests and code review.

Where CodeBakerz fits
To be clear: CodeBakerz programs focus on web development, not on a specific mobile framework. But the Builder program covers exactly the foundations app developers need — programming fundamentals, Git, JavaScript, React, building REST APIs with Django and databases, and team workflow. React skills carry over directly to React Native, and the APIs you build can power any mobile app.
If mobile apps are your goal, Builder is a strong first step. Book a free demo class and ask the mentor how to plan your path.
