You know how many cards you own. Do you know what they are worth today? Most collection apps stop at the inventory: a list, a few ticked boxes. DealDex treats your collection like a portfolio — a value for today, a curve, gains and losses. And soon, with the DexKey, your physical binders will plug straight into it.
A portfolio, not a list
The home screen does not show you a number of cards: it shows you an amount. What your collection is worth today, what it was worth last month, and which cards are climbing fastest.
- Today's value, across all TCGs or game by game.
- Unrealised and realised gains: your sales are counted, not just the theoretical market price.
- Your biggest risers, ranked, price paid against current price.
Scanning: point at the card, it gets filed
No manual entry, no number to copy out. The camera recognises the card, its set and its language, and files it with today's price.
- Recognition by visual fingerprint, not by text: a Japanese or damaged card is still identified.
- You pick the condition, finish and language as you add it — three settings that change the value entirely.
- A catalogue of more than 160,000 cards, five TCGs, six languages.
Condition estimates before grading
Sending a card off for grading is expensive and takes weeks. You may as well know beforehand whether it is worth it. DealDex analyses your card across twelve axes and returns a score out of ten, along with a confidence level based on the quality of your photo.
- Centring: the frame margins are measured against the edges, front and back. It is the one axis that can genuinely be measured, and the most decisive.
- Corners, edges, surface: whitening, dings, scratches. These are estimates, and the app says so plainly rather than passing an approximation off as a verdict.
Price alerts
You add a card to your watchlist with your target price. The app monitors listings and tells you when one drops below it. You open it, you decide.
- Notification the moment the price drops, not the next day.
- Search tuned to your country: marketplace, language and currency.
- Alerts on the way up too, on what you already own, so you know when to sell.
Collections and public page
Organise things the way you actually organise them: by set, by character, or entirely by hand. Each collection shows its value, its progress and its completion rate.
- Collections by set, with a counter for the cards you are missing.
- Collections by character or manual, with a target to reach.
- Share by link, with the amounts hidden if you would rather not show them.
Your profile counts your cards, your gradings and your spending, unlocks badges as your collection grows, and feeds a public page that shows only what you choose.
The DexKey: linking your binder to the app (coming soon)
It is the bridge between the shelf and the screen. Once you have three, five, twelve binders lined up, the problem is no longer knowing what you own — it is finding where, and knowing what it is worth.
What it is
A contactless chip built straight into your DealDex binder during manufacturing. Nothing to slip in, nothing to add: it is part of the binder. Like a transit card, it works without a battery and without charging, and simply carries a unique, permanent identifier that tells the app "that binder there is this one".
How it works
- You hold your phone close to the binder. The chip is recognised, the app opens.
- The first time, you choose which collection this binder matches, or you create a new one.
- Every time after that, one gesture is enough: the right collection appears, with today's value and its completion rate.
What it is for, day to day
- Finding a card without opening four binders.
- Knowing the value of that specific binder, not just of your whole collection.
- Showing your collection to someone: the binder in one hand, the screen in the other.
- Filing a new card and adding it to the right place in the app, in the same movement.
Unlink, relink, pass it on
A collection changes. A binder switches theme, gets sold, gets handed down. The DexKey follows: you can rename the binder, unlink it and link it to another collection as many times as you like, or release it for its next owner. And if you lose the binder, nothing is erased: your collection stays fully accessible. The DexKey is a shortcut, never a required step.
It is built into every custom DealDex binder, at no extra cost — one binder, one chip.
The inventory report for your insurer
Theft, water damage, fire: an insurer will not take a screenshot seriously. The app produces a timestamped document of what you own — photos, certification numbers, price sources and the date they were recorded.
- It is an inventory record, for you to pass on to your insurer yourself.
- You choose the scope: all your collections, only the valuable cards, or a manual selection.
- Annual updates at a reduced rate — insurers prefer a recent inventory.
What it costs, and what it does not do
Scanning, tracking prices, organising your collections and estimating centring cost nothing. Premium lifts the limits for people who collect seriously.
And above all, three things DealDex does not do:
- No advertising: no banners, no video to watch to unlock a feature.
- No third-party trackers: what we measure is our own scan success rate.
- No selling your data: your collection goes to nobody, and you delete it whenever you want.
