Collection Tracker & Inventory vs Shelfii

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, scrapes, or guesses a market price, and it is not financial advice. Catalog what you own, track what it's worth, and watch your gain/loss at a glance.
