About this app

Vault Stacker is a beautifully crafted collection tracker for anyone who keeps
physical collectibles — coins, stamps, trading cards, watches, vinyl records,
comics, sneakers, figures and more. It turns the shoebox and the spreadsheet into
a single, elegant catalogue of everything you own, what it is worth today, and
how your collection is growing over time. No account, no sign-up, no ads — your
collection lives entirely on your device.

At its heart, Vault Stacker organises your collection into vitrines — one display
case per category. Open a vitrine, add an item, and give it a name, photos, a
condition grade, what you paid, and what it is worth now. Every item carries its
own value history, so a quick valuation today sits alongside last year's figure
and you can watch the trend. Tag items, add provenance and notes, and sort each
vitrine by most recent, highest value, condition or year. The home screen keeps
your recently added pieces and your category cases one tap away.

KEY FEATURES
✓ Vitrines by category — coins, stamps, trading cards, watches, vinyl, comics,
books, sneakers, figures, cameras and more, each with its own cover art
✓ Rich item records — photos, condition grading (Mint to Poor), purchase price,
purchase date, current value, tags, provenance and notes
✓ Value history — log valuations over time and see how each piece appreciates
✓ Portfolio dashboard — total collection value, a donut breakdown by vitrine with
percentages, and your top items at a glance
✓ Wishlist — track the pieces you are hunting for with target prices and priority
✓ Fast search — find any item across every vitrine, with recent searches remembered
✓ Custom categories — build your own vitrines with gallery textures, solid colours
or your own cover photo
✓ Backup & restore — export your whole catalogue and bring it back any time
✓ Works fully offline — everything is stored on your device

HOW IT WORKS
1. Open your first vitrine — pick a category to start.
2. Add an item with its photos, condition and value.
3. Watch the portfolio dashboard total your collection and break it down by vitrine.

WHY VAULT STACKER
It is built for collectors who want their catalogue to feel as considered as the
things they collect: a warm, tactile design, real value tracking instead of a
flat list, and complete privacy. No account to create, nothing uploaded, nothing
tracked — just your collection, catalogued.

PRIVACY / DATA
Vault Stacker works fully offline. No account, no tracking, no ads, and nothing
leaves your device.

Add it to your home screen and start cataloguing the collection you have been
meaning to get organised for years.
