A new social collection app designed for football shirt enthusiasts offers a unique platform similar to Letterboxd or Discogs but focuses on football jerseys. The app allows users to create a digital collection of football shirts, earn points for rarity and value, engage with a global leaderboard, connect with other collectors, view a public feed of collections, and participate in direct shirt bidding transactions within the app. Since launching on the App Store with no marketing, the app has gained 53 downloads in just nine days, highlighting strong word-of-mouth interest. The app's monetization model includes a one-time in-app purchase for collection value estimates and bidding capabilities, with the payment system fully verified and configured. The app boasts a clean, documented, and transferable codebase, supporting multiple languages such as Norwegian, English, Spanish, and German. The vintage jersey reselling market is booming, yet no dedicated app has addressed this niche until now, presenting a clear growth opportunity. For prospective buyers, significant growth potential exists as no paid marketing has been leveraged to date. Opportunities include expanding the app to Android platforms, enhancing the bidding feature into a transaction-fee model, forming partnerships with influencers and resellers, and exploring club or league partnerships to expand the rarity system. The current owner developed the app as a side project and is seeking a buyer who can devote the necessary marketing and community growth efforts. Included in the sale are the full source code, backend infrastructure, app listings, third-party accounts, brand assets, complete technical documentation, and personal support during the transition.
