Billing and cancellation
Pro renews monthly or yearly and continues automatically unless it is cancelled at least 24 hours before the period ends. A subscription taken out through the App Store is managed and cancelled in your Apple ID settings, not inside the app.
What the free plan actually does
It is not a trial that closes after two weeks. It stays usable: up to 50 cards in the portfolio, 10 scanner analyses and one pro scan a month, and one set binder. For a collection you can still count, that is enough.
What Pro adds are the things that cost money to run continuously or only matter at scale: price alerts, the automatic drop calendar, portfolio analytics, and unlimited cards and binders.
Why it costs anything
Every scan is an AI call, and every night a catalogue of more than 42,000 variants is re-priced. Both cost money per user. The subscription is the only source of revenue — there is no advertising, there are no affiliate links to marketplaces, and no commission from grading companies. Why it should stay that way.
