Seven things it does.
All of it in real screenshots from the running app — nothing mocked up.
Everything you own, in one place
Every figure recorded once, with quantity, condition and what you paid. Four views onto the same data: gallery, list, table and a deck of cards — plus filters and a search over name, number, theme and notes.

Your collection as a deck of cards
The same figures as trading cards: frame colour by theme, rarity by how widely a figure was released, value along the bottom. The one view that is not there to work in, but to look at.

Value and purchase price, side by side
For every figure the market value new and used — and under it, what you paid yourself. That is the comparison you will not find anywhere else, because only your account knows the second number.
Observed market prices, not an appraisal. A figure nobody has sold in a long time has no price.

One photograph is enough
Camera, file or clipboard — the figure is identified and you tick it off with one click. On a phone the installed app takes a photo straight from the share sheet.
Bag codes of collectible minifigures and custom figures are not read yet.

Lists for whatever belongs together
Your own lists, wishlists, and automatic lists that fill themselves. Each with its count and its value, and the collection's total with its history above them.

One glance is enough
Total value, count, average value and what you have spent altogether. Under it the themes, by value. Deliberately nothing more.

Browse openly, without an account
Whole themes are open on the web, with a progress band per subcategory. Ticking works straight away, the marks stay in your browser, and they move into your account when you sign up.

Start with one figure
An account, no payment details, and the export is ready from the first minute.
