Roundup for eBay sellers
Apps to price thrift finds for eBay
You are standing in a thrift store holding something you have never seen before. These are the apps and tools resellers commonly use to work out what it might sell for on eBay, and what each one does and does not describe on its own pages.
Disclosure: Strooply is made by The Stroop LLC, the publisher of this page, and Strooply is one of the products listed. Every other product name is a trademark of its respective owner. Strooply is not affiliated with or endorsed by any of the other products listed. Their details come from each product's own website, official app store listing, or help page as of September 29, 2026 and are cited below. Plans and features change, so check each product's own site before you decide.
The short answer
How to think about pricing a thrift find
There is no single right tool. Some apps identify and price an item from a photo, some are research databases you search from a desk, and some also carry the item through listing and profit tracking. The table below lists what each product says about itself, with sources. Strooply publishes this page and is one of the products listed.

Choosing
How to choose
- If you want a quick read in the aisle, look for a photo scan that names where its prices come from, and check whether those prices are eBay sales, active listings, or an estimate.
- If you sell mostly on eBay, favor a tool that connects to your eBay account and carries the item through listing and profit, so your numbers include fees and what you paid.
- If you deal in antiques or rare items, a research database with long price history can matter more than a fast scan.
- If you sell on several marketplaces, check which ones each app actually lists on.
- Free trials and free scans are limited, so test a few items you already know the price of before you rely on any estimate.

Questions
Pricing thrift finds FAQ
What is the difference between a photo-scan app and a price guide?
A photo-scan app identifies an item from your camera and estimates a price on the spot. A price guide is a database of past sales that you search. Some products, like WorthPoint, are built around the database; others, like Underpriced AI, Hero, ThriftAI, and Strooply, are built around the scan.[1][4][5][9]
Do these apps use eBay sold data?
It varies. Underpriced AI says it uses an eBay sold-price API first for US and UK scans.[1] Hero says its pricing uses eBay sales and Facebook Marketplace data.[4] Terapeak uses eBay's own sales data.[8] ThriftAI names no specific marketplace on the page we reviewed.[5] Google Lens describes shopping results rather than sold prices.[6][7]
