The best OfferUp alert apps, compared
OfferUp's own alerts fire for related items and accessories. The apps that alert you only for the item you named, with the cheapest plan, the marketplaces each covers and the trial, read from their own sites on October 26, 2026.
The short answer. Deal Scanner: a phone app for iPhone and Android that watches OfferUp, Facebook Marketplace and Craigslist from one search, filters out the accessories and lookalikes OfferUp's own alerts send, takes a low and high price, and buzzes you when a listing is posted with a Deal Score on each find, for $3.99 a month for three searches, cancel anytime. It is built for everyone who checks OfferUp and Marketplace every day, whether flipping is your side thing, your whole job, or not the point at all. The other apps that watch OfferUp are below with their prices, most of them priced for resellers.
OfferUp's own alerts, first
OfferUp has free search alerts and similar-item alerts, both push notifications, set from the bell on a results page or the Set Alert button on a listing. Setup is in how to set up OfferUp alerts. What they send, by OfferUp's own description: for a search alert on "iPhone 15", "other iPhone models, and items related to iPhones like phone cases or screen protectors" too. There is no low price limit and OfferUp does not say how often an alert is re-checked. For a specific item in a price range, most of what buzzes is noise.
