Marketplace Monitor review (2026): what its store listings say, and what it costs to find out

Marketplace Monitor calls itself the app for flippers, scans several marketplaces, and shows no prices on its store pages. What the listings and reviews say, who it is built for, and the $3.99 app with the price on the page.

Checked October 26, 2026. Prices and plans are read from each company’s own site on that date.

Marketplace Monitor is a marketplace alert app on both stores that describes itself as "the ultimate app for flippers," with cross-platform alerts, a dedicated account manager, and a pitch to car dealerships and resellers. It shows in-app purchases but no prices on either listing, so finding out what it costs means installing it. This review is from its Google Play and App Store listings and their reviews, read on October 26, 2026; we have not paid for a plan, and we could not find a website of its own with a pricing page. If you check Marketplace every day, whether flipping is your side thing, your whole job, or not the point at all, the last section is about Deal Scanner, which is ours, with the price on the page: $3.99 a month.

Why we know this app

Marketplace Monitor is the ad I saw first. I sprinted to the App Store to download it, and inside, the cheapest plan was about $30 a month. There's no way that's what this costs. Every competitor I checked was the same or more. So I built Deal Scanner for myself, and then for everyone who had the same reaction.

The in-app price is what we saw when we installed it; it may have changed, and the listings still show none.

What Marketplace Monitor is

From its listings: it scans Facebook Marketplace, OfferUp, eBay, Craigslist, Gumtree "and more," promises notifications "the second a good deal is posted," offers a free trial, and says it started as flippers and provides a dedicated account manager seven days a week. It markets to car dealerships, resellers and individual flippers. Google Play: updated October 20, 2026, over 10,000 downloads. App Store: seller Nicholas Keith Pyne, updated October 25, 2026.

What Marketplace Monitor costs

Neither store listing shows prices; both show "in-app purchases." We could not find a website with a pricing page. The only figure we can point to is a Google Play reviewer in July 2026 who wrote that "£139 may seem expensive" and suggested £99 would be fairer.

What the store reviews say

Google Play: 2.0 stars from 89 reviews. App Store: 3.4 stars from 75 ratings. The Play average is the lowest of any app we track. The positive reviews call it a game changer for spotting items when first posted and praise the customer service. The negative ones are on price, on alerts that did not arrive the second anything was posted, and on billing. Read both stores' one-star reviews before you install.

About the "instant" promise

No app can see a listing before the marketplace itself surfaces it, and Facebook, OfferUp and Craigslist each do that on their own schedule. A promise to alert you "the second" a listing goes up is a promise about the app's schedule, not the marketplace's. Deal Scanner shows the time we found each listing on the alert instead.

Who Marketplace Monitor is built for

Flippers and dealerships, by its own first sentence, with an account manager as the selling point. If you want a human on the other end of your alert app and you run enough volume to justify whatever it costs, that is the pitch.

What everyone else uses

Deal Scanner watches Facebook Marketplace, OfferUp and Craigslist from one search, on our servers, around the clock, and buzzes your iPhone or Android when a listing is posted, with the time we found it on every alert and a Deal Score on each find showing how far under the typical price near you it sits. No Facebook login, no account, no commitment, and the price is right here: Casual $3.99 a month for 3 searches, Hunter $9.99 for 6, Pro $19.99 for 12, all three marketplaces on every plan. It is built for everyone who uses Marketplace, and the alerts work the same whether you buy for yourself, flip on the side, or do it full time. Side by side on Deal Scanner vs Marketplace Monitor; the alternatives list is on Marketplace Monitor alternatives.

A phone lock screen with five Deal Scanner alerts: a riding mower, a leather sectional, an iPhone 14, a 2015 F-150 and a kayak, each with its price and percent below typical — What an alert looks like. Each one shows the price, how far under typical it is, and which marketplace.
