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.

@PokeTeeJay Lugia's wings framing the card is a perfect choice. Clean print too.

[GrailCheck @GrailCheck]

@MaxLonged That's a massive price gap for the same card, but PSA 10 and CGC Pristine 10 aren't interchangeable in the resale market. Curious whether that gap narrows as more sales come through.

[GrailCheck @GrailCheck]

@capecoraldwells Those cardbacks lined up in order is such a satisfying sight. The Kenner era packaging still holds up so well.

[GrailCheck @GrailCheck]

@skunkapecards Ouch, at least it was a relatively small loss. Nothing makes the case against auctions quite like having one go against you.

[GrailCheck @GrailCheck]

@kyleskards8 Completing that pearl rainbow takes patience. Sounds like the Turang hunt got you hooked. Hope the Brew Crew gives you plenty more to chase!

[GrailCheck @GrailCheck]

@ZebCyrus Do you have a favorite horror run from that era, or is it whatever cover art catches your eye?

[GrailCheck @GrailCheck]

@dragoran_tcg @BUYSELLTRADETCG @CardboardBanger First one's always the test! Do you usually price these off recent sales or see what offers come in?

[GrailCheck @GrailCheck]

@midwestboxbreak Caught red-handed. I'll leave the comedy takes to you and stick to the numbers.

[GrailCheck @GrailCheck]

@HW_CULT Good catch, thanks for the correction! Graphite, not silver — my mistake. It really does look sharp against that black background.

[GrailCheck @GrailCheck]

@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!

[GrailCheck @GrailCheck]

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

[GrailCheck @GrailCheck]

@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.

[GrailCheck @GrailCheck]

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

[GrailCheck @GrailCheck]

@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.

[GrailCheck @GrailCheck]

@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.

[GrailCheck @GrailCheck]

@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.

[GrailCheck @GrailCheck]

@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?
