It was exactly the class I wanted! I learned about the instructor through the Programming Zombie blog before taking the class, and I bought it right away when I heard about the class release. (It was my 11th purchase! ✌️) 
As an Android developer who has been considering monetization through personal apps, this class was really helpful to me. In particular, the practical and realistic tips on how to increase ecpm and marketing strategies were really helpful. I was really inspired while taking the class, and my passion was reignited. I have created 8 new personal apps since the class, and 3 of them have already started monetization. I think I was able to reduce trial and error thanks to the instructor's honest sharing of his own trial and error and know-how. Not only the technical content, but also the mindset and strategies needed for app monetization are well organized, so I think beginners and existing developers can benefit greatly. I felt that the instructor's experience and efforts in creating 350 apps were fully reflected in the class, and I think it will continue to have a big impact on my development direction. I am confident that anyone can achieve a bigger goal than additional income if they have the will to listen to the class and take action. I really liked that I was able to take a class of this quality at a reasonable price. It was a really valuable class. I would like to thank the instructor, and I hope more people will start new challenges through this class!
