Free App to Find Value of Items, Whats It Worth Apps Compared

The best free app to find value of items is Google Lens for what something is and Underpriced AI for what it sells for. Google Lens is free and fast but gives no resale price. Underpriced AI identifies the item from a photo, shows the sold listings behind its number, and the first scan is free. Value Scout is a legitimate paid scanner, PriceCharting is the free guide for games and cards, and WorthPoint is the archive for rare antiques.

Disclosure: I built Underpriced AI. Every competitor fact below was checked on the vendor's own page or App Store listing and linked; the date in each row is when.

What's it worth apps compared

The short version: most apps do one job. Lens names the item, PriceCharting and WorthPoint price items you can already name, and the scanners do both. Among the scanners, the question that matters is whether you can see the sales behind the number.

Asking ChatGPT what it's worth, tested

You can, and it is closer than you might expect. We test it every week on our accuracy page: the first photo of items sellers recently sold goes to other AI with no hints, and every answer is scored against the real sale price beside ours. In the September 28, 2026 update, on a $100 item:

So on price alone we tie ChatGPT and beat Perplexity, and Gemini answered too few to call. The real difference is proof. A chatbot gives you a number; 82% of our answers came with the eBay sold listings behind it, so you can check the comps yourself before you sell something for too little. No one prices every item right: on sales where the seller set their own price, half landed within 38% of our number, and vintage, toys and pottery run widest. The page updates every Tuesday.

The 7 best apps for finding out what your stuff is worth

1. Google Lens

Best for: naming an item when you have no idea what it is.

Point your camera at a vase, a painting or an old gadget and Lens finds visually similar items across the web, often with the maker or model. It is free and on most phones already. What it does not give you is a resale value: the prices it shows are retail and asking prices, and a lamp listed at $500 may sell for $75. Use it to get a name, then check what that name has sold for.

2. Underpriced AI

Best for: finding out what an item will sell for when you do not know what it is.

You photograph the item, from vintage jewelry and antique furniture to old toys, designer bags and vinyl records. It names the brand, model, maker's marks and condition, then finds real sold listings for that exact item. Sold prices come from eBay first, through five sources in order, with Poshmark added for fashion, Grailed for vintage clothing, Mercari when eBay sales are thin, and AbeBooks for books. Lots, bundles and wrong variants are filtered out before the price is set.

You get a price, a range, a confidence grade and the sold listings one tap away. If you decide to sell, it writes the listing and publishes it to eBay, and a free browser extension fills it in on Facebook, Poshmark, Mercari, Depop, Vinted, Whatnot, OfferUp and Etsy.

Price: first scan free with no card, then see current plans. iOS, Android and web.

Limits: rare and one of a kind pieces sell across a wide spread, and the result page says so next to the number. Past the first scan it is paid.

3. Value Scout

Best for: resellers of mainstream items who want a photo estimate plus listing text.

Value Scout, from Rhythm App, LLC, is a real and actively updated app: 4.4 stars from 589 ratings on the App Store, and a 4.2 TrustScore from 206 reviews on the Trustpilot page for valuescout.ai. You scan an item, it identifies it and estimates resale value, and it writes a title and description for Facebook Marketplace or eBay. Its listing says it uses "marketplace data, comparable sales, pricing trends, and demand signals."

It is a subscription after the free download: weekly plans at $4.99 and $9.99, and yearly plans from $39.99 to $119.99 on the App Store. Our read: a fair choice for mainstream clothing, shoes and household goods. Before you subscribe, check whether it shows you the actual sold listings for your item, because an estimate you cannot check is hard to trust on vintage and one of a kind pieces. We compare the two in detail on our Value Scout alternative page.

4. What is it Worth? and other "worth" scanners

Best for: a quick photo estimate on common items.

Several App Store apps answer to "what's it worth". The largest we found, What is it Worth? by Web Air AI LLC, has 4.7 stars from 236 ratings, costs $4.99 a month or $29.99 a year for Pro with scan credits from $1.99, and says it uses "comparable sold listings and live metals pricing where relevant." A smaller one, What's it worth on eBay? by Rafael Kolloch (3.5 stars from 73 ratings), averages recent eBay sales and sells 100 identifications for $2.99. Try the free part of any of them on something you already know the value of before paying.

5. The eBay app

Best for: items with a barcode, and free sold price checks by hand.

The eBay app scans a barcode to pull the catalog listing, which is fast for books, sealed games and boxed retail. For anything else, search the item and filter to Sold items to see what it fetched. Both are free. The catch is that most attic, estate and storage unit finds have no barcode, and a sold search only works if you already know what to type.

6. PriceCharting

Best for: video games, trading cards and graded or catalogued collectibles.

PriceCharting is a price guide, not an identifier. Search a game, card or console and you get sold prices split into loose, complete in box, new and graded, which is exactly the distinction that sets value in those categories. The core guide is free. Collector ($6 a month or $59 a year) adds deal alerts, a lot calculator and a photo appraiser; Legendary ($49 a month) adds downloads and API access. It will not help with pottery, glass or general household goods.

7. WorthPoint

Best for: rare antiques and art when you already know what you have.

WorthPoint is the long running archive of past sales for antiques and collectibles, with auction results and a maker's marks library; its own landing page puts the archive at more than 540 million "sold for" prices. When a piece almost never comes up for sale, that history is hard to replace. It has no photo identification, so you need to know enough to search, and it is a paid subscription. Its pricing page returned an access error on September 27, 2026, so check the current price at sign up.

Pricing collectibles: name the exact version first

Collectibles are the hardest thing to value because identification and pricing are one problem. Call a common reissue a first edition and the price is fiction. So work in that order: get the exact version (the mark, the edition, the variant, the colorway), then look at what that version sold for. Google Lens or a scanner gets you the name; a sold comps tool, PriceCharting for games and cards, or WorthPoint for rare antiques gets you the number.

The quickest way to trust any of these apps is to test it on a piece whose value you already know. If it names the exact version and lands near the price you expect, use it on the unknowns.

What makes a good item value app

• Photo identification. The whole point is that you do not know what you have. If you need the name before you can search, it is a research tool.
• Sold prices, not asking prices. Anyone can list a lamp at $500. If every sold listing shows $75, it is worth $75.
• Sales you can see. An estimate is only as good as the comps behind it. Apps that show the sold listings let you catch a wrong match.
• Speed. For a whole house or storage unit you need seconds per item, not ten minutes of searching.

Common items people want to price

Vintage jewelry. Costume jewelry from Trifari, Weiss and Miriam Haskell can be surprisingly valuable, and signed pieces sell well above unsigned ones. Check clasps and backs for marks.

Rare coins. Date and mint mark decide everything, and a key date in high grade can be worth many times a common one. Never clean coins.

Sports cards. Rookie cards drive the market, and a high graded copy can be worth far more than a raw one. Centering, corners, edges and surface all matter.

Vinyl records. First pressings carry the value. A common reissue of the same album might sell for $10.

Antique furniture. Mid century modern pieces lead demand, and maker's labels and stamps add a lot.

Designer handbags. Louis Vuitton, Chanel and Hermes hold value; dust bags, boxes and receipts help.

Vintage clothing. Brand and era matter enormously; see our valuable vintage clothing brands guide.

Vintage toys. Original packaging is the biggest factor. Star Wars, Transformers, LEGO and Hot Wheels are always sought after.

First edition books. The dust jacket can be worth more than the book. Photograph the title and copyright pages.

Vintage watches. Originality beats cosmetics; a scratched original dial usually beats a refinished one.

One sold listing is not a price: what 1.25 million eBay sales show

We looked at every US eBay sale in the Underpriced AI sold-listings archive from July 23 to October 21, 2026: 1,249,971 sales across 20,659 searches that each had at least 10 sales.

• In the typical search, the middle half of sold prices ran about 2.5 times from its low end to its high end.
• In 70% of searches, that middle half spanned at least 2 times.
• Only about 1 in 4 sales landed within 20% of its search's median price.

Some of that spread is real: condition, completeness and timing all move a price. Some of it is the search itself, because a raw eBay sold search mixes lots, variants and different models under one query. Either way, a single sold listing can be off by a factor of two. Match the exact item and its condition, then take the middle of several recent sales. That is the set Underpriced AI shows behind every price it gives.

Tips for the most accurate valuation

Take clear photos in natural light, without flash. Photograph maker's marks, labels and stamps in a separate close up: flip the item and check bottoms, lids, clasps and tags. Capture every side and any damage, and be honest about condition, because chips, stains and missing pieces change the value. Gather the complete set before you scan, since boxes, manuals and matching pieces add value.

Frequently Asked Questions

What is the best free app to find the value of items?

For a name, Google Lens is free. For a free resale value, the eBay app's Sold filter shows what items fetched if you know what to search, and PriceCharting is free for games and cards. Underpriced AI gives one free scan that identifies the item and prices it from sold listings.

Is there an app that tells you what your stuff is worth?

Yes. Photo scanners such as Underpriced AI, Value Scout and What is it Worth? identify an item and estimate its value. Look for one that prices from sold listings and shows them, because asking prices overstate value.

What is the best app to find out what my stuff is worth?

It depends on the item. A photo scanner that shows sold listings suits mixed household finds, PriceCharting suits games and cards, and WorthPoint suits rare antiques you can already name.

Is Value Scout legit and worth it?

Value Scout is a real, actively maintained app with 4.4 stars from 589 App Store ratings. It is worth it if you resell mainstream items and want a photo estimate plus listing text on a weekly or yearly subscription. Check whether it shows the sold listings for your item before relying on it for vintage or unusual pieces.

Can ChatGPT tell me what my stuff is worth?

It can give a number, and in our weekly test it was typically $33 off on a $100 item, the same as us on those sales. What it did not do was show the sales behind the number: 0% of its answers linked a listing, against 82% of ours. Full results are on our accuracy page.

What is the difference between asking prices and sold prices?

An asking price is what a seller hopes to get. A sold price is what a buyer paid. The same item can be listed at $500 and sell for $75, so only sold prices tell you real value.

Do I need to know what an item is before I can price it?

Not with a photo scanner. Research tools like WorthPoint and PriceCharting need the name first; a scanner identifies the item from the photo, then prices that version.

Try Underpriced AI on web or mobile with one item you want to know about: the first scan is free.

How do I know what something is worth to resell?

Look at what the same item actually sold for, not what sellers are asking, and use several sales rather than one: in our archive of 1.25 million recent US eBay sales, only about 1 in 4 landed within 20% of the median for its search. On eBay, search the item and filter to Sold Items; a photo tool like Underpriced AI does that step for you by identifying the item and showing the recent sold listings behind its price. The first scan is free.

How do I find real sold comps for resale items?

The eBay app and website show completed sales when you filter a search to Sold Items, which is the free way and works for anything you can name. When you cannot name the item, a photo scan in Underpriced AI identifies it and lists the sold comps it priced from, so you can open each sale. Asking prices, including most of what Google Lens returns, are not comps.

What is the best app to price items at garage sales and estate sales?

The one that gives you a sold price from a photo in the aisle, because you rarely know the maker or the name of what you are holding. Underpriced AI photographs the item, identifies it and prices it from real sold listings, then shows the net after fees. Google Lens is a fast free way to learn what something is, but it shows retail and asking prices rather than sales.

How can I tell if a thrift store find is worth flipping?

Compare the tag price with what the item sells for after fees and shipping, using sold listings rather than asking prices. Underpriced AI scans the item and returns a sold price range with the fees taken out, so the buy or pass call is one photo. If the sold comps are thin or the spread is wide, treat the number as a guess and price conservatively.

How do I price vintage items for resale?

Identify the exact version first: the maker, the pattern or model, and the era change the price more than condition does. Then price against recent sold listings for that version, not the category. Underpriced AI reads maker marks and labels from extra photos to pin the version before it pulls the comps; WorthPoint is the archive to check for rare pieces.

What is a whats it worth app?

A whats it worth app tells you the value of an item you scan or look up, and the apps do different jobs. Google Lens identifies an item but gives no resale price. Underpriced AI prices from real sold listings, Value Scout is a paid scanner, PriceCharting covers games and cards, and WorthPoint covers rare antiques.

How can I value my stuff for free?

Google Lens is free and fast for finding out what an item is, but it gives no resale price. PriceCharting is the free guide for games and cards. Underpriced AI shows the sold listings behind its number, and the first scan is free.

What should I know about Value Scout reviews?

Value Scout is a legitimate paid scanner, so it is not one of the free options. When comparing it with other apps, check whether the app shows the sold listings behind its number, as Underpriced AI does. Google Lens is free but gives no resale price.
