For the Pokémon Trading Card Game

What your cards are worth, and where the number came from.

The app's shelf value panel for the sample shelf: a total of $31,156, down $2,995 or 8.8% since the last sale, marked TCGplayer in US dollars and labelled an estimate, with what the cards would clear if sold and what they cost.
Totals are estimates from recent sales, not a price anyone has offered you.

What's in it

Your shelf

Priced in one currency, with the date of every price

Add cards as you pull or buy them. The total follows the market, what you paid sits next to what the cards are worth now, and each card's change is measured against its previous sale, since most cards don't sell every day.

Already have a binder? Paste a list of cards and they go in together, each one checked with you before it's added.

A card with no price in your market is counted separately and left out of the total, so it is not quietly treated as worth nothing.

What moved on the sample shelf: a PSA 10 Base Set Charizard down $2,665.26 as the biggest move, then Umbreon VMAX down $325.92, Lugia up $41.41 and Umbreon ex down $29.66, each with its set and grade.
What moved, per card, with the amount and the percentage.
The sets screen: a search box, language filters, and an upcoming set with its release date and how many cards are confirmed.

Sets

English and Japanese sets, and what finishing one costs

English and Japanese sets, how much of each you hold, and what the missing cards cost at today's prices. Announced sets are listed too, with the date and how much of the list is confirmed.

The trade screen sideways: you give $438.77, you get $449.96, with each card's grade and condition and the net if sold instead.

Trades

Both sides priced the same way

The cards you give and the cards you get are priced in one market on one day, with condition counted. It also shows what each side would clear if you sold it instead, which is the real alternative to a trade.

Display mode

Something to show people

One card on the screen at a time with its grade and price. Turn the phone sideways and it adds the whole collection's value, six months of it as a line, and a thumbnail on the day each card arrived. Lock it with a short code before you hand the phone over; the lock lets go after five minutes.

Display mode's collection page: shelf value, cards and sets, a six month line of the collection's value with card thumbnails at each addition, and the best cards ranked.

See it with your own cards. Add one and its price is there, with the marketplace and the day.

A card's history, drawn as it happened

Every dot is one price, placed on the day it was read.

Where sales are far apart, the dots stay apart. A line between them would draw prices nobody paid.

The shaded band is the estimate's range. It gets wider when there is less to go on.

A diagram of how the app draws a card with sparse sales. It shows real readings here once the app has a few months of them.

Where every number comes from

The rules behind each figure ship inside the app too, on a screen called "Where the numbers come from", so they can't drift away from what the code does.

A price
The figure a marketplace published for that exact printing, with its market, its currency and the day it was read. A euro figure is a Cardmarket figure and a dollar figure is a TCGplayer figure. They are not averaged, and the gap between them is shipping, VAT and local demand, not an exchange rate.
An estimate
Worked out from the readings on file for that printing and grade, in one market, and always labelled as an estimate with its range. Where the readings are thin the range widens. A card with no readings of its own gets an estimate on its page and stays out of every total.

The full rules, including graded values and centering, in the app

What it won't do

  • It won't pass a guess off as a price. The big number on a card is the figure a marketplace published, with the day it was read. Where the app estimates, it says so, and a card nobody has sold stays out of your total.
  • It won't predict your grade. The centering tool measures borders. Surface, edges and print lines decide grades too, and a photo can't see them.
  • No tracking. No analytics scripts, no cookies, no ad networks. The app counts things per day, like how often each screen opens, with nothing that says who. Without an account your collection stays in your browser.
  • Card art stays where it lives. Pictures load from the public card database, here and in the app. The names and artwork belong to their publisher.
  • Not investment advice. Forecasts come from the history on file, shown with their range, and they can be wrong.

Questions

Is it free?
Yes, and there is nothing to buy: no paid tier, no trial that ends, no ads and nothing sold on. If that ever had to change so the server could pay for itself, this page would say so first.
Do I need an account?
No. Without one your collection is kept in your own browser, on that one device. An account is for having the same shelf on a phone and a laptop, and whatever you added before signing up comes with you.
Does it work without a signal?
Once it is on your home screen, yes. Your shelf and the last prices it fetched are there, each with how old it is. New prices need a connection, and it tells you when it couldn't get them.
Where do the prices come from?
TCGplayer in dollars and Cardmarket in euros, each labelled with its marketplace and the day it was read. The rules are above.
Is this official?
No. It is a fan-made tool with no connection to Nintendo, Creatures, GAME FREAK or The Pokémon Company.
How often do prices update?
Every night, and again when you open a card that hasn't been checked that day. Every price shows the day it was read, so you always know how fresh it is.
Which cards can I add?
English and Japanese sets, with more languages you can switch on in the app. Graded cards are priced by their grade, and sealed product such as booster boxes has prices of its own.
Can I bring my collection from another app?
Yes. On Add cards, paste a list of cards, one per line, from a spreadsheet or another app. Deskdex matches each line, and anything it isn't sure about is shown to you before it's added.
Is there an App Store app?
No, and you don't need one. Deskdex is a web app: added to your home screen it gets its own icon, opens full screen and updates itself. How to add it is just below.
What happens to my collection if this project stops?
Without an account it is already on your device. With one, Settings hands you everything the server holds about you as a file, and deleting the account deletes it.

Open it and add one card.

That is the whole trial. No account, no email, nothing to install first. If you want to see it with a shelf already in it, the sample is one tap.

It goes on your home screen

Deskdex is a web app, so there is nothing to download. Installed, it gets its own icon, opens full screen, works without signal and updates itself. On any device it's three steps:

  1. Open app.deskdex.app.
  2. Check the address bar says app.deskdex.app, not deskdex.app.
  3. Choose Install, Add to Dock or Add to Home Screen in your browser. The exact taps for your device are below.

Install from app.deskdex.app, not from this page

You're on deskdex.app, the website. Chrome, Edge and Safari can turn any page into an app, this one included, and an icon made from this page opens the website instead of Deskdex. So open the app's own address first, check that the address bar says app.deskdex.app, and install from there.

Open app.deskdex.app

Mac

In Chrome

  1. Go to app.deskdex.app in Chrome, and check the address bar says app.deskdex.app, not deskdex.app.
  2. Click the install icon at the right end of the address bar, a small screen with an arrow pointing down. If it isn't there, open the ⋮ menu at the top right and choose Cast, save, and share, then Install page as app.
  3. Click Install. Deskdex opens in its own window.
  4. It's now in Launchpad and in your Applications folder, under Chrome Apps. To keep it in the Dock, right-click its icon there and choose Options, then Keep in Dock.

To remove it, open Deskdex, click ⋮ at the top right of its window and choose Uninstall Deskdex.

In Safari

  1. Go to app.deskdex.app in Safari, and check the address bar says app.deskdex.app, not deskdex.app.
  2. In the menu bar, choose File, then Add to Dock. You can also click the Share button in the toolbar and choose Add to Dock.
  3. Keep the name Deskdex and click Add.
  4. It's now in your Dock, in the Applications folder inside your home folder, and in Spotlight.

Needs macOS Sonoma or newer. On an older Mac, use Chrome, or just keep Deskdex open in a tab. To remove it, drag Deskdex from that Applications folder to the Trash.

Firefox can't install apps on a Mac, but Deskdex works in a Firefox tab as it is.

Windows

In Chrome

  1. Go to app.deskdex.app in Chrome, and check the address bar says app.deskdex.app, not deskdex.app.
  2. Click the install icon at the right end of the address bar. If it isn't there, open the ⋮ menu and choose Cast, save, and share, then Install page as app.
  3. Click Install.
  4. It's now in the Start menu. Right-click it there to pin it to the taskbar.

In Edge

  1. Go to app.deskdex.app in Edge, and check the address bar says app.deskdex.app, not deskdex.app.
  2. Click the App available icon in the address bar. If it isn't there, open the ⋯ menu and choose Apps, then Install this site as an app.
  3. Click Install. It goes in the Start menu.

iPhone and iPad

In Safari

  1. Go to app.deskdex.app in Safari, and check the address bar says app.deskdex.app, not deskdex.app.
  2. Tap the Share button, the square with an arrow pointing up. If you can't see it, tap ••• first, then Share.
  3. Scroll down and tap Add to Home Screen. If it isn't in the list, tap View More.
  4. Leave Open as Web App switched on and tap Add.

Open it from the new icon. It runs full screen, with no Safari bars.

In Chrome

  1. Go to app.deskdex.app in Chrome, and check the address bar says app.deskdex.app, not deskdex.app.
  2. Tap the Share button at the right of the address bar.
  3. Tap Add to Home Screen, then Add.

Android

In Chrome

  1. Go to app.deskdex.app in Chrome, and check the address bar says app.deskdex.app, not deskdex.app.
  2. Tap ⋮ at the top right.
  3. Tap Install app. On some phones it says Add to home screen, then Install.
  4. The icon goes on your home screen and in the app drawer.

Samsung Internet and Firefox have the same option in their menus.

If something goes wrong

Your icon opens this website?

It was installed from deskdex.app rather than app.deskdex.app. Remove it, then install again from app.deskdex.app. To remove it in Chrome or Edge, open the menu at the top right of its window and choose Uninstall. With Safari on a Mac, drag it from the Applications folder in your home folder to the Trash. On a phone, press and hold the icon and choose Remove.

No install option?

Reload the page once and wait for it to finish loading; browsers only offer to install after that. Private and incognito windows can't install apps.

Where did my cards go?

On an iPhone, and with Safari on a Mac, the installed app keeps its own storage, apart from the browser tab. Cards you added in the tab without an account won't be in it. Make an account in the tab and sign in to the app, and they come across.

How does it update?

On its own. When a new version is ready it says so at the bottom of the screen; tap Reload.

Who makes this

One collector, no company behind it.

Deskdex is written and paid for by one person who collects Pokémon cards and got tired of guessing what a shelf was worth. There is no company and no investor. There are no ads, because an app that tells you what your cards are worth shouldn't also be paid by somebody who wants you to buy more.

The server keeps counts per day, like how many sessions there were and which screens got opened, with nothing that says who. The privacy page says exactly what is kept.
