This course is prepared for Basic Learners.

What you will learn!

  • App monetization

  • App marketing

  • A system for prolific creation.

  • Boost app productivity

  • Boosting productivity with AI

I created 350 apps while sleeping only 4-5 hours a day.

We're revealing the process by which I earned 7 times my salary!


A steady monthly income from app development

You must have thought about it at least once.

I also thought that if I just made a good app, the profits would naturally come in.

But the reality was not easy. I barely managed to maintain a daily income of less than $0.5 for 8 months.

As time went by and I dug around a lot, I realized that there are guides to making money with apps.


Since I realized that, my profits have been steadily increasing.

As the belief that “it is difficult to make money with apps” is broken,

You will find that "if I invest time, I will get a corresponding return."

So I worked at the company for 6 years while developing my own app.

In the process, we developed about 300 apps,

As revenue generated from the app increases from 2 to 7 times the monthly salary,

Now that I've quit my job, I can live comfortably and create the services I want.

Now in my 7th year of app development,

During this time, I created a lot of apps and went through a lot of trial and error.

In the process, I wasted a lot of time unnecessarily.

I hope that others will not have to go through these trials and errors, so I am sharing the know-how and strategies that I have accumulated.

I would like to share it in a lecture.


“Why are you sharing this valuable information?”

Many people may be skeptical. "Why would you disclose such valuable information? Wouldn't it be more beneficial to keep it to yourself?"

I thought the same thing at first.

Actually, creating the lecture was a big challenge for me.

Because revealing my know-how means increasing the number of potential competitors . So, from the time of lecture production to just before release, I thought a lot about whether I should produce the lecture or release it.


But my blog

As I posted in https://soulduse.tistory.com/106 , this path is lonely. There aren't many people who make money with apps, but now I have a small wish that there will be more people walking the same path as me.

"Isn't it just missing the core elements and not having much content?"

This is proven by the 161 course reviews and the 5.0 rating. If it was simply a lecture that deceived with poor content, it would never have received such an evaluation.

More importantly, what I want to convey is not a simple 'secret to success'. This lecture is not a 'fish-catching' lecture that recommends a specific app or category. That approach can be dangerous. Because the moment a certain field is known to be profitable, numerous competitors jump in and the market quickly becomes saturated. Instead, what I am conveying is 'how to catch fish'.

  • How to discover profitable app ideas

  • Effective monetization strategies


  • Practical marketing know-how

  • A system that creates sustainable income

  • A multi-app system that maximizes productivity


This knowledge has real value as it can continue to be applied even as the market changes.

This course is not one that will allow anyone to easily earn 10 million won per month.

If you search a little these days, you'll see a lot of articles and YouTube videos claiming, "Anyone can easily earn 10 million won a month."

But isn't it strange?

The fact that anyone can easily make a lot of money means that there is literally no such thing as a moat .

Such items may be effective before or at the beginning of sharing content, but soon countless people will start following suit, and items that earn 10 million won a month will no longer have any meaning.


This course does not guarantee that you will earn 10 million won per month.

But what you will gain from this course is clear.

If you internalize the content of the lecture and practice it consistently, I believe you can start with an income of $1 per day and gradually achieve significant additional income, and even an income higher than your monthly salary.

If you are hesitant about the price of the course,

The cost of the course may seem burdensome. But think about it for a moment. If you divide this course fee by 365 days, it is about 1,000 won per day. What I can confidently tell you is that if you practice what you have learned in this course, you can easily earn $1 per day. In the end, even if you earn only $1(약 1400원) per day, you will earn more than the course fee in a year.

More importantly, the value of time. I have accumulated these know-hows through countless trials and errors over the course of 7 long years. Through this course, you can skip the countless mistakes and inefficient processes that I have experienced. In the end, this course will be an investment that will pay for itself and save you a lot of your precious time and energy.

It's time to get rid of the illusion that "if you make a good app, the money will follow." The most important truth I've learned while developing countless apps is that no matter how great your technology is and how perfectly you make your app, if you don't know how to monetize it, you won't make a single penny.

I will share with you the countless thoughts and experiences I have had while developing personal apps. Leverage your precious time and energy!

"Isn't that something you achieved because you excelled?"

I have been working for a company for almost 8 years, but I am not an outstanding developer. I have hardly studied algorithms, and it would have been difficult to even apply to a company that has a coding test. Since I have achieved this, people with similar or better skills will be able to achieve results faster.

For 6 years out of the past 7 years, I lived two lives simultaneously as an office worker and a personal app developer. My day didn't end after I left the office. I would come home, have a quick dinner, and then sit down at my computer again to work on my personal app.

I endured only 4-5 hours of sleep a day, and poured all my passion into app development without weekends. You can check out my journey on my blog and GitHub commit history . With the obsession to write at least one more line of code every night, I have created over 350 apps.

Through numerous trials and errors and failures, I was able to gradually establish my own system for which apps can survive in the market and how to generate revenue efficiently. Now, I have learned how to generate stable revenue through a strategic and systematic approach, not just by creating many apps.


I will share with you the thoughts and experiences I have had while developing countless personal apps.


Learn about these things

1. Mindset important for monetization

No matter how good your technology is or how well you make your app, monetizing it is a separate issue. Learn what kind of mindset you should have when approaching it.

2. Monetization method, marketing method

If you work hard to build an app but don't know how to monetize or market it, you may not make any money. Learn how to monetize and market the app you worked hard to build.

3. Optimization process for prolific app production

How did we manage to create 350 apps?

Learn about systems that will help you maximize your app productivity.

This course is currently the cheapest available.

I would like to especially emphasize that the current course prices are the lowest.

1. Continuous improvement of lectures

This course will not be a one-time content, but one that will continue to evolve and grow. Based on feedback from students, we will supplement necessary content and provide additional new lecture videos that address frequently asked questions.

2. Reduce potential competitors

By revealing my know-how through this course, I may increase my potential competitors, which may ultimately affect my earnings. In the same vein, those who take this course will also face an increasing number of competitors as time goes by.

Considering this reality, the course prices will increase gradually over time. This is not simply a matter of increasing revenue, but also a strategic choice to protect the potential interests of current students. Therefore, I can tell you that now is the best time to take the course at the most reasonable cost.

I have put a lot of thought and effort into this book to make it rich. Create more income than your company salary through one-person app development, and live the life you want. This journey that took me 7 years, you will be able to achieve in a shorter time.


Moreover, as the burden on development skills has decreased due to the advancement of AI, I hope this lecture will be helpful for your new challenge.

Frequently Asked Questions

Q. I lack development skills... Can I really make money with an app?

  • A. The biggest misconception about app monetization is that it requires ‘excellent development skills.’ What I’ve learned from creating 350 apps is that ‘strategy’ is more important than ‘technology’ in successful app monetization.

Q. I know how to code, but I don't know what kind of app to create.

  • A. Don't worry! It's okay if you don't have any ideas right now.

    I'll tell you in detail about many of the ways I come up with ideas.

Q. Can you teach me how to develop an app and how to code it?

  • A. This course does not teach coding. There is a reason for this.

    Anyone can create an app, but not everyone can make money with it.

    Can you give me an example?

    • You can learn app development knowledge for free by searching on YouTube or the Internet. And there are already many high-quality lectures.

    • But the know-how to make real money with that app is nowhere to be found.

    This course focuses solely on ‘app monetization’ and ‘productivity’ for it.

    • Monetization strategies and practical know-how

    • From app ideation to marketing

    • A strategy to maximize the productivity of app development and increase exposure in stores.

    Because the real challenge isn't creating an app, it's making money with it.
