Frequently Asked Questions
How does listing analysis work?
+
Paste an eBay listing URL for a CGC- or PSA-graded Pokémon card into ArbLab. We pull the listing price and compare it against current market value for that card and grade, then show you the profit and ROI if you bought and resold it -- including whether re-grading at a higher tier is worth it.
How do subscriptions work?
+
ArbLab offers Pro and Premium subscriptions, each with monthly or annual billing, purchased through your Apple ID via the App Store. Pro unlocks unlimited listing analyses and the Watchlist. Premium adds Portfolio tracking, batch scanning, and alerts on top of everything in Pro. You can compare plans and prices any time from Settings.
How do I cancel my subscription?
+
Subscriptions are managed through your Apple ID, not inside ArbLab. On your iPhone or iPad, open Settings, tap your name, then Subscriptions, select ArbLab, and tap Cancel Subscription. You'll keep access to Pro/Premium features until the end of the current billing period, then automatically drop to the free tier.
How is profit and ROI calculated?
+
Profit is the estimated resale value at the target grade minus the listing price and any grading fee. ROI is that profit divided by your total cost (listing price plus grading fee), shown as a percentage. These are estimates based on recent market data, not a guarantee of what a card will actually sell for.
