I am a developer working on developing a space journal application. During the development process, I encountered several crucial strategic and technical decisions, and I would like to hear the experiences of those who have gone through similar situations. Here are the simplified versions of several questions I have. Resource allocation: Which problem should I address first? Design direction: In terms of interaction and UI design, how should I balance "immersion" and "usability"? Market selection: Was it easier for a business to survive in the early stages as a B2B or B2C entity? Cost estimation: How can I reasonably present to my investors the development costs of this project? In order to avoid relying solely on intuition in my decisions, I created a short questionnaire, hoping to gather more structured opinions from my colleagues. If you are also exploring VisionOS, I sincerely hope you can take a few minutes to fill it out. The results are extremely important to me, and I would be more than happy to share the final summary findings with you.
