Built by auction buyers, for auction buyers. Every feature exists because we needed it ourselves.

The Bid Ladder
An auto-generated ladder shows the total cost at every auction increment from the low estimate up. Rows turn green (within budget), amber (near limit), or red (over). A MAX BID marker shows your ceiling. Tap any row to set your bid instantly.
If the auction is in a different currency to your home currency, a third column automatically shows the equivalent in your currency at the current ECB exchange rate — so you always know what you're paying in the money you think in.

Live Auction Mode
When your auction is running, tap Go Live for a dedicated bidding screen. Compact lot info at the top, the bid ladder filling the screen, and Won/Lost/Pass buttons fixed at the bottom. Tap any ladder row to set your bid. Auto-advances when you close each lot. Auto-ends when all lots are done.
The live price bridge works with the-saleroom.com and EasyLive — when the extension is connected, the auctioneer's asking price updates your ladder automatically. For all other platforms, tap the current bid manually as the auction runs.
This app does not place bids — it's a visual calculator to help you bid smarter. You still bid on your auction platform as normal.

Browser Extension — Search, Save & Live Bridge
The free extension does three things. Search: find lots across 7 platforms simultaneously — the-saleroom, EasyLive, eBay, Invaluable, NumisBids, iCollector and LiveAuctionWorld — with Featured Auctions and one-click saving. Save lots: a 🔨 Save Lot button appears on every lot page on the-saleroom and EasyLive, and you can save from search results and Featured catalogues too — export as PDF or CSV when done. Live bridge (optional): pairs with this app to feed the auctioneer's asking price to your bid ladder in real time during auctions — the asking price highlights automatically as bidding moves. It never modifies pages or places bids.
Desktop only. Without it, Live mode works manually — the ladder is fully functional, you just update the current bid yourself.

Import lots from any auction platform
Three ways to add lots — paste a single URL via + Add Lot and everything is extracted automatically (lot number, description, estimate, image, auction house, fees) from any supported platform. Or use ⬆ Bulk Import to paste a list of URLs and import an entire sale at once. Or install the free browser extension to get a 🔨 Save Lot button across all 7 platforms as you browse — save as many as you like, download the list, and bulk import in one go.

Auction house profiles
Save each house's fee structure — BP%, additional premium, online fee, minimum buyer's fee, VAT rate, and mode. Set custom bidding increments per house (standard, fine art, fixed £1/£5/£10, or your own table). Always verify fees against the sale T&Cs before bidding.

Per-lot fee overrides
Each lot can override the auction house defaults. For EasyLive lots, the all-in rate (buyer's premium + internet surcharge + VAT) is applied automatically based on your registration type — adjust per lot if a specific lot has different VAT treatment. Toggle VAT on hammer for lots not under the margin scheme, add Artist's Resale Right (UK or EU sliding scale), and enter additional costs like storage, shipping, or import duties.

🚦
Traffic light budget warnings
Set a budget per lot and watch the colour change in real-time. Green when safe, amber near your limit, red when you're over. Never accidentally overspend.

Contextual help tooltips
Every field and section has a ? icon. Tap it to see a plain-English explanation of what each setting does — buyer's premium, VAT modes, ARR, bid increments, and more. No need to open the help guide.

📱
Works on any device
Runs in your browser — nothing to install. Works on iPhone, Android, iPad, laptop, desktop. Designed mobile-first for use in the saleroom. Add it to your home screen for a full-screen, app-like experience.
Note: the Live Bridge browser extension requires Chrome or Firefox on desktop — it is not available on mobile. On mobile, Live mode works manually — the bid ladder is fully functional, you just update the current price yourself. For the best live bidding experience, use a desktop with the app and auction platform open side by side.
