ScryDeck charts collection value at two levels: per-card price history when you inspect a printing, and account-wide portfolio history across every daily snapshot.
-
Per-card price history
Open any card from your collection or search and switch to the price history tab in the detail drawer.
Free accounts see the last 7 days. Pro unlocks week, month, year, and all-time ranges back to 2012. Locked ranges show a Pro badge — tap to upgrade.
-
Portfolio history chart
Pro users can view an all-time portfolio chart on `/home` showing owned market value, acquisition cost, and realized value over time.
The chart aggregates daily snapshots into weekly points so long histories stay readable.
-
Home widget vs portfolio chart
The Home widget is the at-a-glance view — today’s owned value and status breakdown. Available on Free.
The portfolio chart is the long-horizon view — how your entire library trended over months and years. Pro only.
-
When snapshots update
Adding, removing, or changing cards triggers a refresh of today’s snapshot in the background. You do not need to manually recalculate value after scanning a batch.
