Collection Tracker & Value

⭐ Catalog any collection, track what you paid against what it's worth, and see your real gain or loss — all on your own phone.

This app is a private, manual collection tracker and home inventory organizer — an app for tracking collections built 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. Trading cards, LEGO, vinyl, coins, Funko, comics, watches, sneakers, action figures, statues, manga, retro consoles, sports memorabilia, fine art, wine, jewelry — catalogue any hobby or collection of belongings in one list.

🔒 PRIVACY FIRST — NO ACCOUNT, NO SIGN-UP, 100% OFFLINE
Works entirely offline. No login, no linked accounts, no backend. Your collection — including photos — stays on your device and is never uploaded. Your numbers, your collection.

📋 CATALOG ANY COLLECTION
• Track any collectible: trading cards (TCG, graded, slab-mint condition), LEGO, vinyl, coins, banknotes, bullion, numismatic and philately pieces, Funko Pop, comics and manga, watches, sneakers, stamps, action figures, statues, keychains, sports cards (rookie cards, autographed jerseys), retro consoles and discs, plush, dolls, books, and more
• Log what you paid (cost basis), what it's worth now (current value), condition or grade, an acquired date, notes, and a photo
• Give each item a name and a quick badge (a letter or an emoji), organize by category, tag freely, and browse by storage location or display shelf
• Keep a hunt list — a wishlist with target prices for the pieces you're chasing, ready for when you're ready to trade or sell

💰 SEE YOUR COLLECTION'S TRUE 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, and filter or search once your list grows
• Every re-value builds a per-item value history and sparkline, so you can watch each piece trend over time
• You enter both the price you paid and the current value — this app never scrapes or guesses a market price or price guide for you

🔔 REVALUE REMINDERS & LOAN TRACKING
• Set an optional reminder to re-check the value of high-value or rare, limited items every so often
• Lend a piece out and set a due-back reminder so you always know who has it
• 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
