Cross-listing for iPhone and Mac

List once.
Sell everywhere.

Snap a photo and ListSync's AI writes the listing, reads the price sticker and picks the right category on every marketplace. Then it posts for you, in the background, while you keep working.

Posts to the first seven for you. Vinted, Etsy and Grailed open with everything filled in for you to paste.

Tap Post, then get on with your day.

Pick the marketplaces, tap Post, and the screen closes. A bar at the bottom shows each marketplace going live: Facebook done, eBay uploading photos, Poshmark waiting its turn. If one of them fails, it tells you why and gives you a Retry button. You don't sit there watching a spinner.

ListSync fills in each marketplace's own form for you, category and all, using the login you made once inside the app. It never has your marketplace password.

ListSync Listings screen showing where each item is live

One list of everything you're selling.

Each item shows the marketplaces it's live on. Every few minutes ListSync checks them. When something sells, you get an alert right away, it's marked sold on Facebook for you, and the alert shows where else to pull it down with one tap. That's how you avoid selling the same fridge twice.

Already have listings up? Import them from Facebook, eBay, Poshmark or Mercari and they join the list.

ListSync Inbox with buyer messages from three marketplaces

Buyers from every marketplace, one inbox.

Facebook, Nextdoor and eBay chats land together, with offers flagged so you see the money first. Turn on Auto-reply and ListSync answers "Is this still available?" for you, in your words, and tells you it did.

And the rest of it.

The Post screen: marketplaces the item is already on are checked; Nextdoor and Poshmark selected with their categories shown — **Post to more places later.** Open any listing and add marketplaces. Ones it's already on are greyed out, so it never gets posted twice. Each new one shows the category it'll go under, and you can change it before posting.

The Dashboard: revenue, items sold, and a chart of sales by marketplace — **Know where the money comes from.** Revenue, items sold and average sale, split by marketplace and by month. Filter to one marketplace to see if it's worth your time.

The Assistant: a chat that answers questions about prices and your listings — **Ask it anything about your stock.** What's selling fastest, what a used fridge goes for, what to list next. It knows your listings and looks things up on the web when it needs to.

The small things

Reads the price sticker: Point the camera at the tag and the price is filled in. No sticker? Tap Check what it sells for to see what the same item actually sold for lately.
A whole shelf at once: Take photos of everything, and ListSync sorts them into items. Drag a photo to another item if it guessed wrong.
Titles that get found: eBay, Poshmark and Mercari get a keyword-packed title. Facebook and OfferUp get the friendly one.
Right category on each site: Facebook, OfferUp, Nextdoor and Poshmark each get their own category, shown before you post so you can change it.
Mac and iPhone: Sign in on both and your listings, photos and sales stay in sync. Leave the Mac app open and it watches for sales all day.
Seven languages: English, Español, Русский, Українська, 简体中文, Tiếng Việt and 한국어. Your listings stay in whatever language you write them in.

Free for three days, then plans from $5 a month. Billed by Apple; cancel from your App Store subscriptions any time.
