Marketplace Monitor scans Facebook Marketplace, OfferUp, Craigslist, Gumtree, eBay and more for profitable phone listings, then alerts you when matching deals appear. Filter by exact iPhone model, submodel and price range so you only see phones that fit your buy box.
Phone flipping is competitive — underpriced phones get snapped up in minutes. Marketplace Monitor gives you the edge by scanning marketplaces and instantly alerting you to matching listings via phone or Discord, so you’re first to act.
Marketplace Monitor helps you cut through the clutter by showing only the phones you actually want to see. Instead of wasting time scrolling past irrelevant listings, you can zero in on profitable deals faster. Build a search with precision. Choose the exact manufacturers, models, and even sub-models you’re looking for, and let Marketplace Monitor do the heavy lifting.
Manually checking platforms like Gumtree, Craigslist, or OfferUp is time-consuming. Marketplace Monitor combines all listings — including Facebook Marketplace — into one clean view, helping you find deals instantly.
Most marketplace apps rely on basic keyword searches. That means a search for “iPhone 15” can still bring back cases, chargers, broken listings, old models, unrelated phones, or sellers using messy titles.
Marketplace Monitor lets phone flippers build more precise searches by choosing the exact iPhone series, model and submodel they want to track — such as Base, Pro or Pro Max.
Instead of scrolling through irrelevant listings, you can focus on the phones you actually want to buy and resell.
A good price for an iPhone 11 is not the same as a good price for an iPhone 15 Pro Max. Marketplace Monitor lets you set different min and max prices for each model, so your alerts only trigger when a listing matches the margin you are looking for.
