About

Your collection, properly kept. Adding a piece takes seconds. Search by name, product code or barcode, pick the exact variant, and it arrives with its photo, year, series and scale already filled in. The catalog holds more than 200,000 records: diecast cars, LEGO sets, figures and trading cards. Nine out of ten have a photo. WHAT YOU RECORD Condition, quantity, boxed or loose, and your own photos. Purchase price and private notes stay private. They never appear on your profile, in the feed, or anywhere another collector can reach. HOW FAR ALONG YOU ARE Follow a series and Shelvo counts for you. Three of fifty. One piece short. When you get close, it says so. YOUR SHELF Pin a collection to your profile. Put your most treasured pieces up front and write a line about why each one matters. What other collectors see is a shelf, not a spreadsheet. LISTS A wishlist, a themed list, a list of the ones you are still hunting. Make one public and other collectors can follow it. THE FEED New series arriving in the catalog, collector fairs coming up, a piece from years back, and what the people you follow are showing off. Choose the categories and brands you care about and the feed leans that way instead of showing you everything. BROWSING By category, by decade, by theme. The time tunnel walks back through release years. Barcode search works, so you can scan the back of a package and land on the exact release. EVENTS Collector fairs and meetups, with a countdown on the ones you follow. Already keeping a spreadsheet? Bring it in as CSV instead of typing it again. Turkish and English, the whole app. Shelvo is in beta. It changes fast right now, and what you tell us decides what gets built next. support@shelvo.app Shelvo Pro is an auto-renewing monthly subscription. It renews unless cancelled at least 24 hours before the end of the period; manage or cancel it in your App Store account settings.
