Underpriced AI alternatives: resale value apps and how each one charges
Short answer: the main alternatives to Underpriced AI on iPhone are ThriftAI and Pocket Pricer for pricing a single find, Flippr for scanning a whole pile and listing on eBay, and Cluzy for quick thrift checks. The free route is eBay's own Sold items filter. Honest Haul (coming soon) is built for the moment before you pay: a price range with how sure it is, the most to pay, and Buy / Maybe / Pass, with no account.
What Underpriced AI is

Which one to pick
- You sell on several marketplaces and want inventory tools: Underpriced AI or Flippr.
- You bring home boxes and lots: Flippr, which identifies several items in one photo.
- You want the cheapest weekly plan: Pocket Pricer lists Pro at $2.99 a week.
- You only check a few finds a month: the free eBay Sold items filter, plus the free eBay profit calculator for the fees.
- You want a fast yes or no in the aisle, without signing up: Honest Haul.
Where Honest Haul is different
- A decision, not just a price. Enter the tag price and it shows the most you should pay and a Buy / Maybe / Pass call.
- A range with its confidence. Low, typical and high resale prices, the reasoning, and what to photograph or check next when it is not sure.
- Check it yourself in one tap. Opens a real eBay sold-listings search for the item it identified.
- No account. Your scan history stays on your device. A scan that cannot identify the item does not count against your 3 free scans.
- A trial you can see coming. On the yearly plan's free trial, the app offers a reminder the day before it ends.
- From any screenshot (iOS 26). Use visual intelligence on a screenshot or the camera and send the item to Honest Haul.
Honest Haul is coming soon to the App Store. Until then, the free guides on this site cover the same math: how much to pay at a garage sale to resell, what sells best from garage sales on eBay and how to check eBay sold prices while thrifting.
Cancelling an App Store subscription
Subscriptions bought in an iPhone app are managed by Apple, not by the app: open Settings, tap your name, tap Subscriptions, choose the subscription and cancel at least 24 hours before it renews. Subscriptions bought on a company's website are cancelled on that website.
