About these guides
Short, direct answers to the questions people ask before they start: whether you need to know how to code, how an AI builder differs from drag-and-drop no-code tools, how long a first version takes, and when a web app is enough versus a real Android app. Every answer ends with what to try next, so you can go from a question to a working app in the emulator preview in the same sitting.
