What changes after free usage
The paid plans are for repeat use, not a different product
The first 3 total scans are there so you can test how the result format handles likely type, era clues, value direction, and caution notes.
Weekly and yearly plans remove the starter limit and support continued scanning when you keep returning to the app for more pieces, more comparisons, and saved finds you want to revisit.
This is useful when your use is ongoing, not when you only need one quick answer and never expect to come back.
