How can startup app ideas be validated before development?

Validating startup app ideas before development is crucial to avoid wasting time and resources. Start by conducting market research to understand your target audience and their pain points. Create surveys or interviews to gather feedback on the concept. You can also build a simple MVP (Minimum Viable Product) or landing page to test interest and collect sign-ups. Another option is to run targeted ad campaigns or use crowdfunding platforms to gauge potential demand. Early feedback ensures your app addresses real needs and can be adjusted before full development.
