Use revenue estimation tools to validate market size before entering

Before building, use tools like Sensor Tower to estimate competitor revenue and confirm the market supports viable businesses. Look for niches with multiple apps doing $50K+/month to derisk market size concerns.

When choosing which market or app category to enter, especially for mobile apps where revenue data is available through estimation tools

Don't do this
