Photograph a minifigure. Find out which one it is.
Point the camera at a minifigure and FigDex matches it against a catalogue of 17,068 of them. It answers with what it can see: one figure when it is sure, two or three side by side when the difference is a printed detail, or the character with all its variants when the photo does not show enough. It does not guess.
It does not price anything. There is no dollar figure anywhere in the app, because a guessed valuation is a number nobody can check and every collector would be right to argue with. Rarity is four labels worked out from the catalogue — how old a figure is, how many sets it came in, whether it was a blind bag — and the rule is printed in the app so you can disagree with the arithmetic rather than with a number that came from nowhere.
