Appark is an all-in-one platform for mobile app market intelligence and competitor research. It helps you analyze downloads, revenue, and rankings across any app, compare competitors side by side, and discover early-stage apps with growth potential.

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. The key advantage: surveys are fetched server-side, meaning you can create, edit, and update questions instantly without waiting for Apple's review process. 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. Built for Swift and SwiftUI apps, FeedbackWall integrates in under 5 minutes via Swift Package Manager. The real-time dashboard shows response analytics, trends, and geographic distribution. Starting at $19/month - significantly more affordable than enterprise alternatives like Survicate ($299+/mo), Sprig ($175+/mo), or Pendo ($1,250+/mo). Ideal for: iOS developers, indie app makers, bootstrapped startups, and product teams building mobile-first experiences.
