Who It's For

Built for Resellers Who Source In Person

FlipperHelper is the profit tracker for people who buy secondhand items to resell. Whether you're a car boot sale flipper in the UK, a flea market seller in the US, a charity shop reseller sourcing for eBay, or a Vinted and Depop side hustler in Canada or Europe — this app replaces the messy spreadsheet you've been using to track what you bought, where you listed it, and how much you actually made.

Unlike cross-listing tools, FlipperHelper doesn't post items for you. It tracks the entire lifecycle — purchase, listing, sale, expenses — and shows your real profit after all costs. Entry fees at the market, petrol to get there, the item price, and the final selling price on any of 16 platforms. That's the number that matters.

FlipperHelper is free to download with no ads. Every current feature is available at no cost. Read our privacy policy and terms of use.

The Story

From First Commit to App Store in 31 Days

FlipperHelper started because my wife needed a better way to track her car boot sale flipping business. She was using Google Sheets — and it was painful. So I built an app.

Day 1 — first working version: take a photo, log a price, save to JSON. Day 7 — multi-currency support and Google Drive photo sync. Day 14 — expense tracking, Money Flow analytics dashboard, and listing reminders. Day 18 — migrated from JSON files to SQLite for performance. Day 23 — complete Figma design system, every screen redesigned. Day 28 — onboarding flow, background sync, and full data backup/restore. Day 31 — production app with TestFlight beta, live on the App Store.

What started as a weekend hack became a real product. The entire app was built by one developer, with AI-assisted development using Claude Code.

How is FlipperHelper different from Vendoo or Flippd?

FlipperHelper is a profit tracker, not a cross-listing tool.
