We partnered with Nerd HQ at FanX for a live celebrity charity game. TurnZero HQ ran the table: live scores for the packed hall and for everyone watching the stream.

It's the same app you use on a Friday night.

Nothing special was built for the stage. It's the tracker you'd put on your own table.

A one-minute tour: scanning cards into a priced collection, building a deck from the cards you own, tracking a game at the table, and following your playgroup. The sections below go through each part.

01 · Collect

Keep every game's collection in one list.

Most collections live in boxes at home, where you can't check them during a trade. TurnZero HQ puts the list on your phone, sorted by game and priced from the market.

Scan it in

Point your camera at one card or a spread of them. The app finds the set and printing and adds each card.

Know what it's worth

Live market prices on every card, with a running total per game and across all of them.

Know where every copy is

In a deck, in a binder, or spare. Your decks and your collection are the same list, so nothing is counted twice.

Sort it how you sort it

Make binders for your trades, your sell pile and the cards you want.

The deck page explains your deck, and Ask TurnZero answers questions about it.
02 · Build

Build decks from the cards you own, and see how they hold up.

Every game has its own rules for a legal deck and its own idea of a good one. The deck builder knows both, and it knows what's already in your collection.

Built from what you own

See which cards you already have, which are in another deck, and what you'd still need to buy.

Legal before you sleeve it

Deck size, copy limits and format rules checked as you build, for the game you're building in.

Read back to you

The app shows your curve, points out gaps, and flags cards that aren't doing much, with the reason for each.

Bring the list you have

Import from the sites you already use, or scan the physical deck. No typing card names.

03 · Play

Track your games and see which decks win.

Every playgroup argues about whose deck is best. When you track your games, you get a win-loss record for each player, each deck and the group as a whole.

Keeps score in any game

Track life, lore or prize cards, depending on the game, on any phone or tablet at the table.

Decks that earn a rating

Each deck gets an Elo-style rating from its wins and losses, ranked in your group and globally.

Head-to-head records

See your record against every player you've played with.

Whole nights, whole rooms

Run several tables at once with one set of standings, and put it all on the TV.

04 · Connect

Keep up with your playgroup and trade with other collectors.

Your friends list, your group's history and your trades work across every game in the app.

Your playgroup, kept

Your friends, your shared game history and a group leaderboard that carries over from week to week.

Moments

Post a big play while the game is going, and your friends can react to it.

Follow along live

If you can't make it, you can follow the scores and standings from home.

Trade with collectors

Put both piles side by side and see how they weigh up, or share your trade binder with a link.

Common questions

Which games does TurnZero HQ support?

Magic: The Gathering, Pokémon, One Piece, Yu-Gi-Oh!, Disney Lorcana and Riftbound. Collecting, deck building, game tracking and the social side work the same way in each.

Can I keep more than one game in the same account?

Yes, and that's the point. One account holds every game you collect and play. Each game's cards, decks and records stay separate where they should, and your collection value and friends list cover all of them.

Is it just a life counter?

No. It keeps score as well as any counter, but every game it tracks goes on the record: deck ratings, head-to-head records and your group's history. It also keeps your collection and builds your decks.

Does it work for game stores and big nights?

Yes. One night can hold as many tables as you need, with balanced pairings, one set of standings across the room, and TV mode for the wall.

Is TurnZero HQ free?

Yes. Collecting, deck building, tracking games and connecting with friends are free on iOS, Android and the web. The phone apps show occasional ads and the web app shows none. Premium, at $5 a month, removes the app ads and adds AI-written recaps, collection value history and higher limits. It does not remove the display ads on these guides.

Use one app for every game you play.
