Underpriced AI and FlipTip do the same core job: name an item from a photo and price it from real eBay sales. They differ in how many scans you get for the money, which countries they serve and what comes after the price.
We make FlipTip. Facts about other tools come from their own websites and app store listings, checked November 2026 — sources at the bottom.
Pick Underpriced AI if you want native iPhone and Android apps, up to 12 photos per scan, specialist sources such as Discogs, AbeBooks and Grailed, or scan packs that never expire. Pick FlipTip if you scan a lot (a daily allowance instead of 20–50 scans a month), sell outside the US and UK, or want the buy-or-skip maths — Deal Score, the most to pay, what to offer the seller — on every scan.

Both apps publish how their prices compare with real sales, but they measure differently, so the numbers cannot be set side by side. Run the same five items through both on your next trip and compare with what they actually sell for.
Point your phone at any item: FlipTip identifies it, shows what it actually sold for, your profit after fees and a clear buy-or-skip. Free plan (3 photo scans a day) · Starter $1.99/mo (40 scans a month, any day) · Hustler $9.99/mo (15 scans a day, up to 450 a month) · Flipper $19.99/mo (40 a day, up to 1,200) · Dealer $39.99/mo (90 a day, up to 2,700) · Flipper free for 5 days for new accounts, no card.
Scan an item freePer scan, usually yes. Underpriced AI's plans run from $5 a month for 20 scans to $99 a month for 750 (checked November 2026). FlipTip's Hustler plan is $9.99 a month for up to 15 scans a day (450 a month), and the Free plan gives 3 photo scans a day. For a few items a month, FlipTip's Starter plan is $1.99 for 40 scans a month with real sold prices — about $0.05 a scan; unused scans don't carry over, while Underpriced AI's packs never expire.
No. Underpriced AI (underpricedai.com) says on its own site that it is not affiliated with underpriced.app, a separate company with a similar name.
FlipTip runs in the phone browser on iPhone and Android and installs to the home screen like an app, so there is nothing to download from an app store. Underpriced AI has native iPhone and Android apps.
Both compare their prices with real sales and publish the result, but with different methods, so the figures are not directly comparable. FlipTip's blind test, its method and every single test are on its accuracy page.
