アイデア創出と検証の方法

This lesson is about idea validation: how to find good app ideas and, crucially, check they are worth building before you sink in the effort.

Great ideas hide in everyday life. Mine your own frustrations, tedious tasks, fresh tech trends, and apps you wish worked better. Start by observing.

Flip the question with a problem-first approach: not “I want to build an app” but “what problem can it solve?” Avoids the classic solution-in-search-of-a-problem trap.

Once you have a problem, brainstorm every possible solution without filtering. “I forget to water my plants” could be a reminder, an ID app, or a smart sensor.

Run each idea through a quick filter: is it a real problem for others, is the market big enough, can you build it, and are you genuinely excited?

Do light market research: scan the app stores for rivals and reviews, check Google Trends for interest, and see if forums discuss the problem. Gauge demand fast.

Competition means a market exists, so learn from rivals: study their features, pricing, and reviews to find the gap or angle that makes you better.

You do not need a full app to test demand. A fake-door test is a simple landing page; count signups to a waitlist to measure real interest cheaply.

The strongest validation is talking to 5–10 potential users about their problems and how they solve them today. Listen more than you pitch.

Understanding how to validate your ideas early is crucial for indie hackers. Let's test your knowledge on this process.

Recap: start with a problem, brainstorm broadly, filter fast, scan the market and rivals, then validate with fake-door tests and real user conversations.
