In this Base44 tutorial, I show you how to go from a blank screen to a live, published web app—without writing a single line of code. I build a fitness planning and tracking app as the example, but the workflow applies to basically any internal tool or client-facing product you want to ship fast. We walk through onboarding, the dashboard layout, and the core idea behind Base44: you describe what you want in plain English, and it generates the app, database, and logic for you. The biggest takeaway is that the tool is only as good as your prompt. I explain how I structure prompts to reduce ambiguity, and I use a simple checklist (who it’s for, what actions they take, what data you need, and what screens/forms are required). Then I test the generated app, catch real issues (like metric vs US units), and show how I iterate—when to use visual edits (free, no credits) versus the AI chat (costs credits). I also cover adding user authentication, navigating the backend (Users, Data, Integrations, Code), and finally publishing to a public URL with “require login” turned on.
