What is FlipperHelper?

FlipperHelper is a free iOS app for people who buy secondhand items at car boot sales, charity shops, and flea markets, then resell them on platforms like eBay, Vinted, and Facebook Marketplace. It tracks every item from purchase through listing to sale and calculates your real profit after all expenses.

Built by Oleksandr Prudnikov, a Ukrainian developer living in Wandsworth, South West London. He made it for his wife after she started reselling and had no way to track what she was buying, where she was listing it, and whether she was actually making money.

About the Developer

Oleksandr Prudnikov

Software developer from Ukraine, living in Wandsworth, South West London. Built FlipperHelper after his wife started buying items at car boot sales and charity shops to resell on eBay and Vinted. She turned it into a proper business but had no way to track what she paid, where things were listed, or what her real profit was. So he built her an app.

FlipperHelper took about six weeks to build and is completely free. No ads, no subscriptions. Just a useful tool for regular people who flip things on the side and want to know if they're actually making money.
