Mobile App

Laminapp

iOS app for World Cup sticker collectors to track collections and coordinate trades.

React NativeSupabasePostgreSQLTypeScriptExpo

Overview

Laminapp is a mobile app published on the App Store for the World Cup sticker collecting community. Collectors track their collection state and the system automatically matches them with other users for trades — eliminating the chaos of managing swaps manually through social media groups.

Problem

Sticker collectors manually track missing stickers in notes or spreadsheets, then coordinate trades through social media groups with no matching system. Finding someone who has your missing sticker and needs one of your duplicates is a manual, time-consuming process with no dedicated tooling.

Solution

A React Native mobile app where collectors register their collection state (owned, missing, duplicates) and the system runs automatic two-way matching — finding collectors where both parties can complete a beneficial trade. Supabase powers real-time updates and auth.
