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
