It's great for learning React Native.

I was curious about the local DB implementation, and since this was exactly what I needed, I purchased it right away. haha I went through it a bit quickly, focusing on the parts I was curious about. It's really great because the lecture contains only the essentials without any fluff. I'll enjoy the rest of it. Thank you for the great lecture.

Since it was expo, I was able to complete it more easily than the map app.

There is a lack of overall explanation of the lecture content. You mentioned that the short lecture time is an advantage, but you moved through the material so quickly without even a brief explanation of the packages used, making it very difficult for someone new to mobile development to follow along. Throughout the entire lecture, I felt like I was just transcribing the instructor's flashy coding show rather than actually learning something. Of course, the completed app from the practice session is very polished and the code is clean, but that's because of the instructor's excellent skills. If a student were to develop such an app on their own, the content explained in this lecture alone would not be sufficient. This lecture seems suitable for those who have prior knowledge of mobile development and want to quickly go through the entire practical development process from start to finish. If you don't have mobile development experience, I think you should give it more thought before enrolling.

There are cases where the code changes in between without explanation. It's not drastically different though..
