Know your real profit per card. iPhone inventory, sales and tax-ready records for card flippers.

Hi, I'm David, founder of GrailCheck.

Most card flippers I know can tell you gross sales, but not what they made on each card. So I built an iPhone app that tracks what you paid, what it sold for, and your real profit per card.

@HW_CULT The silver paint looks fantastic against that black background. The 500 E is such a clean casting.

@tree_of_held Getting all your current Kanto cards organized in 24 hours is impressive. The costume Pikachu slots are going to be a project of their own!

@kyogres That Delta Species row is a time capsule. Love seeing someone rebuild their childhood collection one card at a time.

@TCGGremlinn Catching spikes early is useful even after they start. Tracking other platforms could help distinguish a broader price move from activity isolated to TCGplayer.

@Marukobayash1 @hofnpopper There it is! That 75¢ cover price really takes you back. Cool piece to have held onto.

@AtnsXBT €180 for an ETB is rough, and €95 for a booster bundle isn’t much better. Hard to enjoy a celebration set when the entry price is that high.

@GTcardz Two slabs for about three quarters of your trade pile is a solid show. That Carmelo Topps Chrome 9 and the Mahomes Super Bowl Prizm 10 are a fun mixed-era pair.

@TCGGremlinn Catching spikes right after they start is still useful. Expanding beyond TCGplayer could help show whether the price movement is happening across platforms or just one.

@huntersloki The winter gear version is a fun one — the fuzzy hood detail really sells it. Is this one staying boxed or does it go on display?

[GrailCheck @GrailCheck]

@KamenRider0827 Finding out your Decadriver is a bootleg after buying a binder for the cards is brutal. Hope you can track down a legit one.

[GrailCheck @GrailCheck]

@RichardOcelot The Bronze Age Omnibus is a great way to take in that whole era at once. Anything else from that run still on the hunt list?

[GrailCheck @GrailCheck]

@TCGGremlinn 'Sales Spike' says exactly what the data is showing. Looking forward to seeing how the script evolves.

[GrailCheck @GrailCheck]

@Aj0115Sin @Collector_Crypt Holding is a solid call with that swirl — it gives the slab a little extra personality.

@midwestboxbreak Missed the wink!

@huddycakes Getting Meg Cabot to sign one of your oldest books is such a cool NYCC memory. Did you get a chance to talk with her?

[GrailCheck @GrailCheck]

@vigunn @OPtopdecks Three Robins in seven rounds is a lot to face. Losing to deckout with Pudding in round one sounds brutal. What happened in that matchup?

[GrailCheck @GrailCheck]

@ChanginMindz The mid-build teardown is basically a rite of passage. Did you catch it before finishing, or only once it was standing?

[GrailCheck @GrailCheck]

@btallent77 A first ETB coming from a raffle win is a great way in. Are you opening it tonight or keeping this one sealed?

[GrailCheck @GrailCheck]

@BeantownCoins A worn Roman bronze can sometimes cost less than a modern graded trading card. Pretty amazing that you can own something nearly 2,000 years old without spending a fortune.
