Best apps to check Gundam card prices
Five iPhone apps compared on the question a price check depends on: which source the number comes from, whether it is for your exact version, and how often it updates.
GunTomo is made by Lucernel.

Short answer
For a price you can trust, check the source and the version: GunTomo names its source (public TCGplayer data) and prices the exact version of a Gundam card, including LR+, LR++ and parallels. Among apps you can install today, GNDM TCG Dex names TCGplayer and Yuyu-tei with daily updates, and TCGplayer shows its own marketplace prices.
Choose this if
Choose GunTomo when the exact version and a named price source matter most and you collect Gundam only.
Choose GNDM TCG Dex or TCGplayer if
You want to install an app today, and PriceCharting or Collectr if you also track other games.

How we chose: We looked for iPhone apps that show a price for Gundam Card Game cards and ranked them on five criteria, in the order a price check depends on them: whether the app names the source of its prices, whether it prices the exact version rather than the card number, whether it states how often prices update, whether it names the Gundam Card Game, and the price and privacy label listed on the App Store on October 1, 2026. Facts about other apps come from their App Store pages and are dated by that day. GunTomo is made by Lucernel, the publisher of this site.
Where the number comes from
A price is only as good as its source. Some apps show the price of live listings on a marketplace, some show what cards sold for, and some do not say. Of the five apps here, GunTomo names public TCGplayer data, GNDM TCG Dex names TCGPlayer and Yuyu-tei, TCGplayer uses its own marketplace, and PriceCharting uses recorded sales from auction sites. Collectr does not say on its App Store page.
Two sources can disagree, and neither is wrong. A marketplace price reflects what sellers ask now, while a sales price reflects what buyers paid. When the amount matters, compare two.
The exact version, not the card number
A Gundam card can exist as LR, LR+ and LR++ under one card number, and the rules treat them as the same card in play. Collectors price them separately, so an app that gives one price per card number can be wrong by a lot for an alternate version. Our guide to telling the versions apart shows how to read the rarity line first.
Of these apps, only GunTomo describes pricing the exact version, including parallels and promos. For the others, check that the entry you are looking at matches the rarity mark and art of your card.
How often prices update
Only GNDM TCG Dex states a frequency on its App Store page: daily price updates. The other pages say nothing about how fresh the numbers are, and Collectr calls its database real-time without naming a source. Treat any price as a snapshot and check the date before you buy or sell.
Our suggestion for a quick sanity check: open the card in two apps, compare the version and the number, and only then act on the difference.
Cost and privacy
The four installable apps are free to download. TCGplayer lists no in-app purchases, GNDM TCG Dex, PriceCharting and Collectr sell paid tiers, and GunTomo's official page has current store details. Privacy labels are self-reported by developers and not verified by Apple. PriceCharting lists data not linked to you, TCGplayer and Collectr list data linked to you, and GNDM TCG Dex lists data used to track you.
Frequently asked questions
What is the best app to check Gundam card prices?
For an exact-version price from a named source, GunTomo. For an app you can install today, GNDM TCG Dex or TCGplayer.
Why do LR, LR+ and LR++ have different prices?
They are different versions with different art, and collectors price them separately even though they play the same. Check that your price is for the right version.
Is the TCGplayer price the real price?
It is the market price on the TCGplayer marketplace. Other places, including Yuyu-tei and auction sales, can show different numbers.
Do these apps update prices every day?
Only GNDM TCG Dex states daily updates on its App Store page. The others do not state a frequency, so check the date before you act.
Is GunTomo available?

Our pick
GunTomo, the price of the card you hold
A price check goes wrong when the number is for the wrong version or the source is a mystery. GunTomo reads the card code on the iPhone, tells LR, LR+, LR++, parallel and promo versions apart, and shows the market price of that exact version from public TCGplayer data, in the currency you choose. It is made for Gundam collectors and sellers who want the version and the source in one scan. Card text and images belong to Bandai; GunTomo is an independent app.
- Exact variant detection, including parallels and promos
- Market prices from public TCGplayer data
- Collection by set with copies and total value
