Everything you need to write about FlipperHelper.
What is FlipperHelper?
FlipperHelper is a free app for iOS and Android 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.
