Aim2Build helps you get more from your LEGO collection.
Instead of searching through instructions, Aim2Build starts with your inventory and shows you which sets you can build — and how close you are to completing others.
What you can do
- Add and save your LEGO inventory
- See clear buildability percentages
- Find sets you can already build or are close to finishing
- View missing parts at a glance
Aim2Build is designed to be fast, simple, and practical — whether you’re a casual builder or a serious collector.
The web version is free to explore.
The iOS app offers optional Pro features for users who want deeper insights and faster decisions.
