'Can I make an app by myself?'

AI has provided an answer to this question that everyone has probably thought about at least once.
The era of one-person development has arrived, where even non-experts with no coding experience can manage everything from planning to development, store launch, and even advertising revenue generation on their own, as long as they have an idea.
A book has been published that presents a detailed roadmap from planning to launch.

In the past, app development was often frustrated by technological barriers such as Java, Kotlin, React, Flutter, and Firebase.
However, the emergence of generative AI tools such as Cursor AI and ChatGPT is completely changing the development paradigm.
What matters now is not the complexity of the technology, but how actively we collaborate with AI to quickly turn ideas into reality.

This book accurately captures these changes of the times.
Readers will learn 'Vibe Coding', a new development method for the AI ​​era, by creating their own Pomodoro timer app, 'Focuslet'.
'Vibe Coding' is an innovative development method that allows users to request AI in human language, such as "create this function," and obtain code without having to know any programming concepts.

The book's journey begins with the planning stage of defining the MVP (Minimum Viable Product) of the 'Pomodoro Timer' with ChatGPT.
Afterwards, we set up a development environment including Flutter SDK and Android Studio, and begin full-scale coding with the AI ​​code editor, ‘Cursor AI.’
In this process, readers learn the principles of collaboration, using AI not as a simple code generator that quickly creates the results humans want, but as an "AI pair programmer" and "personal tutor" that helps solve problems and completes the results together.

AI is no longer an option, but a necessity.
This book proves that anyone can become a "creator" through collaboration with AI, and is expected to be a significant turning point leading to the popularization of individual development.
