About

I’m a solo developer based in Seoul, South Korea, developing for iOS and Android. I’m a Vibe Coder, and before that, I spent over 10 years crafting handmade shoes. Now, I’m very interested in distributing and marketing apps after they’re released.

What actually moves distribution in the first weeks after shipping? Two-week observation

Following up on the first post in this series and the thread it kicked off on app distribution. I ran a two-week observation on organic distribution and want to bring the results back for discussion, not conclusions. Translation tool was used again, so please read past awkward phrasing.

The reason I am posting again : the same question that came up last time is still open for me, and I now have two weeks of data that only made it sharper. I would rather test my reading against yours than sit on it.

My extremely personal Vibe Code diary

Hello, fellow Vibe Coders. I am a new Vibe Coder who left the handmade shoe industry in Korea to embark on a startup journey. I d like to share a record of the past two months or so.

As I am Korean, I am using Google Translate to generate the English text for each paragraph; I ask for your understanding.

1. In the two-plus months since I started using Claude Code, I have built nine simple apps; I released three of them on iOS and five on Android. This count includes projects I abandoned midway because they became too difficult.

2. The total number of downloads is just over 200, and I ve generated one paid subscription and $15 in AdMob revenue. These are the results from June through July. I hope this post will serve as a record of my early, modest beginnings.

Today, I gave AI some advice on writing.

Although I don't have a background as a developer, I m really enjoying the process of building and deploying multiple apps using "Vibe Coding." While it isn't generating revenue right now, I do feel a sense of accomplishment. What I want to highlight here is the interesting dynamic involved in how these apps gain visibility.

I formulated the following hypothesis: if someone watches the video for my app, they will actually purchase or download the app.

AI can understand my app and create automated videos.

I formulated the two hypotheses mentioned above and proceeded to analyze YouTube videos using Claude Code, create an avatar video using my own selfie, record footage on an actual device, and generate narration by creating a Korean voice sample (since I do not speak English)
