FeedbackWall is an iOS SDK that lets mobile app developers collect user feedback through in-app surveys without App Store resubmission. Unlike traditional feedback methods (email surveys, feedback portals, App Store reviews), FeedbackWall delivers 15-25% response rates by asking users directly inside your app at the right moment. Perfect for indie iOS developers and small teams who need to understand why users churn, validate feature ideas, or prioritize their roadmap based on real user data.
