How FlipperHelper Works

Three steps from market find to real profit.

📸

Buy

Snap a photo at a car boot sale, flea market, or charity shop. Log the price, market, and seller. FlipperHelper generates a unique SKU automatically.

🏷️

List

Mark which platforms you've listed on — eBay, Vinted, Facebook Marketplace, Depop, and 12 more. Track listing dates and asking prices across all of them.

💰

Profit

Record the sale and FlipperHelper calculates your real profit after entry fees, transport costs, and currency conversions. No manual spreadsheet formulas. See all features ↓

💱

Buy in GBP at a UK car boot sale, sell in USD on eBay US. Supports USD, EUR, GBP, and CAD with automatic daily exchange rates from the European Central Bank.

🧾

Expense Tracking

Entry fees, transport (car, bus, train, taxi, van, bike rental), and other costs — all tracked per market trip. Your profit calculation includes everything.

📴

Offline-First

Works perfectly at markets with no WiFi. All data is stored locally on your iPhone. Sync to Google Drive when you're back online — it's completely optional.

☁️

Google Drive Backup

Photos upload to your Google Drive automatically in the background. Export your inventory as a CSV that converts to a Google Sheet for spreadsheet analysis.

📍

Smart Markets

GPS auto-suggests nearby markets when you open the app. Track which sellers you buy from, set geofence radii, and see spending per market over time.

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 completely free. No subscriptions, no in-app purchases, no premium tiers, no ads. Every feature is available to every user 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.
