FlipperHelper

FlipperHelper is an iOS app for people who buy and resell second-hand goods. Track items from purchase to sale across 16 selling platforms including eBay, Vinted, Depop, and Facebook Marketplace.

Photograph purchases, log costs, track where items are listed, and see your actual profit after entry fees, transport, and platform fees.

Built offline-first — works at car boot sales and outdoor markets with no phone signal. Data stays on your phone with optional Google Drive backup and automatic Google Sheets export.
