My LEGO Portfolio
Add your sets and the price you paid. We fetch the real market value and your ROI.
Scan a box
Use your phone camera to scan a LEGO box barcode and add the set to your portfolio in one tap, no typing.
Tap the button below and allow camera access when your browser asks.
Frame the barcode printed on the LEGO box. We read it automatically, no need to press anything.
We identify the set and drop it into your portfolio. Just add the price you paid and you're done.
Works best on Android Chrome. On iPhone, Safari doesn't support live camera scanning yet, so tap the button and type the set number instead (it's printed right next to the barcode).
