Most app ideas are wrong. Not slightly off. Not "needs refinement." Wrong. And now AI has made it easy to turn a bad idea into a polished, working app in a weekend-complete with login screens, dashboards, and features nobody asked for. You can build it. That doesn't mean you should. DON'T BUILD THAT YET is a brutal, practical filter for one question:Is this idea actually worth building-or are you about to learn an expensive lesson?Inside, you'll learn how to: Tell the difference between a real problem and one that just sounds good Identify who would actually use-and pay for-your app Validate demand using behavior, not opinions Spot when your "technology problem" is actually a people problem Avoid the hidden costs that quietly kill solo-built apps Know when to keep building-and when to stop This is not a book about coding.
It's not about tools. It's not about building faster. It's about not building the wrong thing. Whether you're sitting on an app idea, already deep in a build, or wondering why what you shipped isn't working-this book will force you to face the one thing most builders avoid: reality. Because the most expensive mistake in software isn't building something badly. It's building something nobody needed.
Includes chapter-by-chapter checklists and ready-to-use AI prompts to pressure-test your idea at every stage.
