Read full descriptionHide full description
ShelfRadar watches trading card and collectible restocks across the biggest retailers and shows you what just came back in stock, in one live feed, updated around the clock. No account. No sign-up. No subscription. Open the app and everything is there. LIVE RESTOCK RADAR See sealed product coming back in stock as it happens, with the retailer, the price we saw, and how long ago it landed. Filter the feed by category to cut it down to what you actually collect. FREE RESTOCK ALERTS Turn on the categories you care about and get a notification when something hot comes back in stock. Alerts are free and require no account. We keep a push token and your chosen categories, and nothing else. No email, no location, no profile. IN-STORE MAP See where items are actually hitting shelves. Search by ZIP code, city, or state, filter by store, and tap a pin to see what landed, which store, and when. Directions open in Apple Maps. The app never asks for your location. You type where you want to look. RELEASE CALENDAR Everything releasing now, plus a month by month calendar of what's coming. Know the street date before it arrives instead of finding out after it sells out. CARD INTEL Real market data, not guesswork. Worth Chasing: sealed product trading above MSRP, with the spread. Price Movers: what's climbing right now, and by how much. Grading Upside: raw versus PSA 10 prices, and the multiplier between them. RESTOCK FORECAST How often each product actually comes back, how long it's been since the last restock, and the cadence we've measured over the past two weeks. CATALOG SEARCH Search every product ShelfRadar tracks across all supported retailers. COVERAGE Thousands of tracked products across thousands of stores, monitored continuously, online and in store. WHAT WE TRACK Pokémon, One Piece, Magic: The Gathering, Disney Lorcana, Yu-Gi-Oh!, sports cards, and more. A NOTE ON LINKS When an item links out, it opens the retailer's own website, where the retailer handles the purchase. ShelfRadar never takes a payment and never handles your card. Some retailer links are affiliate links, which may earn us a commission from the retailer at no cost to you. ShelfRadar is not affiliated with, endorsed by, or sponsored by any retailer or card manufacturer. Product names and trademarks belong to their respective owners.

DropSync gives collectors a fair shot at the drop. Sealed trading cards and hot collectibles sell out in seconds. DropSync watches the major retailers around the clock and pings your lock screen the instant a restock goes live — then puts you one tap from the buy button, before the crowd even finishes refreshing. WHAT THE APP DOES • Instant restock alerts — the moment stock hits at Target, Walmart, Sam's Club, or Pokémon Center, your phone knows. No refreshing, no F5, no luck. • The GO screen — one tap takes you straight to the product at the retailer, signed in and ready to check out. Timing is everything, and this is the fastest path there is. • Upcoming drop windows — see when each retailer tends to drop, with honest confidence labels. A pattern is never dressed up as a promise. • Collect-what-you-want filters — get alerted only for the categories you care about (Pokémon, Lorcana, One Piece, sports, and more) and mute the rest. Your choices sync to every device. - Scan and track your entire Pokemon collection ONE MEMBERSHIP, MORE FIREPOWER DropSync Plus follows you everywhere for one price: • On your phone — the instant alerts and GO handoff above. • On desktop — the DropSync browser extension, including the precise-refresh sniper that times your checkout down to the millisecond inside your own logged-in browser. • In the community — a collectors Discord for drop-night intel. HONEST BY DESIGN DropSync handles timing and information — you click checkout. We never store your retailer logins, we never auto-buy for you, and we're not affiliated with any retailer or brand. You stay in control of your own purchases in your own logged-in browser. YOUR COLLECTION, ON YOUR PHONE • Scan to add — point the camera at a card and it's identified, priced, and logged. Recognition runs on your device, so the photo never leaves your phone. • Graded slabs — the label is read for you, grade and certification number included, and priced from real observed sale medians rather than a model. • Honest prices — every number says what it is: an observed market price, an estimate, or "not enough sales to say". Nothing is rounder than the data behind it. • Have, Want, Selling — three piles, cost basis, notes, and a portfolio total you can audit. • Set completion — see how close you are, closest-to-done first. DROPSYNC PLUS PRICING • Monthly — $12.99/month • Annual — $129.99/year (best value) Subscriptions renew automatically until canceled; manage or cancel anytime in your App Store settings. Payment is charged to your Apple ID at confirmation of purchase. Privacy Policy: https://dropsync.chasedex.com/privacy Terms of Use: https://dropsync.chasedex.com/terms
