Your Unofficial Riftbound TCG Companion
Point your phone at a card to identify it instantly, organize cards into collections and decks, track your collection's market value, and record game results to see your win rate over time.
Point your camera at any Riftbound card. The app recognizes it in under 2 seconds and shows the card details with current market price. Add it to your collection with one tap.
Use Fast Mode to rapidly swap cards in front of the camera - each card is automatically recognized and added to your collection without any taps.
Organize your cards into collections - binders for your physical cards, wishlists for cards you want, or any custom grouping. See your total collection value at a glance. Track both regular and foil versions separately.
Build decks with automatic format validation. The app checks your deck against Riftbound rules and tells you if something's wrong (too many copies, missing Legend, wrong deck size). Organize cards into sections like Legend, Champions, and Sideboard.
Import and export your decks for seamless integration with other web or mobile applications.
Record your games to track performance. Log the opponent, outcome, and optional notes. See your win rate per deck and overall stats on the home screen.
Track player scores during in-person games, regardless of format or pod size. Add up to 5 players, adjust scores individually with tap or swipe gestures, and keep a running tally throughout the match. Perfect for tracking points across multiple rounds or game formats.
See current market prices from Cardmarket (EUR) and optionally USD. Your collection value updates automatically when prices change. Tap any card to jump directly to its marketplace listing.
Everything works without internet. Your collection, decks, and game history are stored on your device. The app syncs card data and prices when you're online, but your personal data never leaves your phone.
Card database (names, images, stats, set information) sourced from the public Riot Games Riftbound API.
Our server fetches the full card list once daily. The mobile app syncs from our server on launch if newer data is available.
Server: Azure Blob Storage (static JSON files)
