The only Pokémon TCG app that builds your deck AND checks it for mistakes — before you get to the table. DECK BUILDER Build 60-card decks with intelligent search that finds any card by name, set, or card number. Add energy with quick-tap buttons. When you're done, tap Check for Mistakes and the app validates everything: • Card count (exactly 60) • 4-copy rule • Basic Pokémon requirement • Missing energy types for your attackers • Broken evolution chains • Standard format legality (regulation marks) • Trainer reprint rules (old Boss's Orders? Still legal.) Export your deck list as an official-format PDF, ready to hand to a tournament judge. TRADE CHECKER Stop guessing if a trade is fair. Enter any two cards and get an instant verdict based on live TCGPlayer market prices. The screen turns green (fair), yellow (you're getting more), or red (you're giving too much) — so you know at a glance. Type a set name or code — autocomplete finds it. Or tap the Binder button to pick a card you already own. Use Autofill Best Deal to find the best combination of your trade-tagged cards that matches what they're offering. BINDERS Organize your physical collection into digital binders. Search by name to add cards, tag them as "track" or "trade", and see live market values update automatically. Your binders sync across all your devices. FEATURES • 21,000+ cards with daily price updates • Full card art on long-press • Search by name, set name, set code, or card number • Newest cards shown first • Works offline (decks stored locally) • Syncs binders and decks across devices via iCloud • Dark mode holographic UI Pricing data sourced from TCGPlayer via Scrydex.
