I am a backend developer with no experience in app development. So at first, I was very hesitant about taking the course, and in the end, I decided not to. I thought the course was too expensive for the amount of time it would take, and I thought that I didn't know enough to take it now and that I would just wait until later. However, I kept thinking about it and changed my mind and decided to take it again. The reason I changed my mind was that I wanted to launch my own app this year, so I thought it was important to set a direction, so I decided to take the course. My impression after taking the courses is that 'you don't have to be afraid of the price'. Of course, I think the course is expensive. That thought hasn't changed since before I took it and now that I've completed it, but if you ask me if it was worth the money, I would say that it was worth every penny. The instructor shares a lot of the trial and error he has gone through over the years and teaches us how to improve each step of the way, and he teaches us a variety of things that we would never know as developers. I think this is a course that anyone who wants to monetize their app development should take. Time is the most important thing, and I think I was able to leverage my time a lot with the cost of the course. I'm also looking forward to the courses that will be released or added in the future. As for improvement points, there are a few lectures where the volume of the instructor's voice is a little different, but that's about the only thing that needs improvement. The content is really valuable.
