Collection Tracker & Value

This app is a private, manual collection tracker for anyone who wants a clear record of what they own and what it's worth. You enter the numbers yourself, so the app never asks for an account, never connects to a server, and never leaves your phone. Cards, LEGO, vinyl, coins, Funko, comics, watches, sneakers — track any collection in one place.

The hook is the whole-collection rollup: see your total value, total cost, total gain or loss, and your overall portfolio ROI the moment you open the app.

— KNOW WHAT IT'S WORTH —
• An instant collection-value rollup: total value, total cost basis, total gain/loss, and overall ROI
• Per-item gain/loss and return, colored so wins and losses are obvious at a glance
• Sort by value, by gain, by acquired date, or by name; search and filter by category as your list grows
• You enter both the price you paid and the current value — this app never scrapes or guesses a market price
• Analytics: value by category, cost vs value, and your top movers
• Full per-item value history over time

— CATALOG ANY COLLECTION —
• Track any collectible: trading cards, LEGO, vinyl records, coins, Funko Pop, comics, watches, sneakers, stamps, action figures and more
• Log what you paid (cost basis), what it's worth now (current value), condition, an acquired date, notes, and a photo
• Give each item a name and a quick badge (a letter or an emoji), and organize with your own custom categories
• No limit on how many items you track

— PRIVATE BY DESIGN —
• No account, no sign-up, no backend
• Your collection, photos, and history live only on your device and are never uploaded
• Works fully offline — lightweight, old phones welcome
• Export your whole collection to CSV any time

— REVALUE REMINDERS —
• Set an optional reminder to re-check the value of high-value items every so often
• Reminders are scheduled on-device; no push server, no tracking
• A passed reminder is simply shown as due and clears when you update the item

— A HANDY RECORD FOR INSURANCE —
• A documented photo plus cost and current value for every item
• An at-a-glance proof-of-ownership picture of your whole collection, useful for insurance and estate records

— A NOTE ON WHAT THIS IS —
this app is a manual record-keeping tool for hobbyists. The values are the ones you enter yourself; this app never appraises
