OpenHolo

Check prices. Scan slabs. Review sales. Manage your collection. Everything in one professional-grade app.

OpenHolo is built for card collectors. It brings marketplace pricing, real sales, PSA data, scanning and collection management into one clear, powerful interface, helping you understand card values and market movement faster.

ALL MARKETS, ONE CLEAR VIEW
Market data from SNKRDUNK, eBay and other sources is brought together in one view. Ungraded cards and each PSA grade are shown separately, so you can compare the same condition without checking every marketplace yourself.

MORE THAN THE ASKING PRICE
Explore sales trends, PSA population by grade, Gem Rate, market liquidity, seller photos and active listings. You see more than a single price. You see the sales activity and available supply behind it.

POINT. SCAN. FIND THE CARD.
Point your camera at any card or a PSA label to instantly find the matching card and pricing data. Ungraded cards, different languages and any orientation are all recognized, and you can import a photo to find several cards in a single shot. Scan multiple cards in sequence and add them to your collection in one action, cutting out repetitive searches and data entry.

PROFESSIONAL-GRADE COLLECTION MANAGEMENT
Record the quantity and grade of every card while your collection value updates automatically with market data. Add cards you are considering to your watchlist and keep everything clearly organized.

NEVER MISS YOUR PRICE
Set a target price on any card you are watching and get notified when a sale reaches it, or when a new listing appears. Pause alerts one at a time and resume them whenever you like.

NO SIGN-IN REQUIRED. SYNC WHEN YOU WANT.
Core features work without signing in, and your data stays on the device. Sign in with Apple or Google to sync your collection and watchlist across devices, then restore them after moving to a new device.
