Every cat you meet is a discovery waiting to happen. CatDex turns cat-spotting into a cozy collecting game: snap a cat, find out what breed it is, and build a collection that's entirely yours. SNAP ANY CAT Take a photo or pick one from your library. CatDex shows the three closest breeds with confidence scores, what gave it away (the ears, the coat, the eyes), and a fun fact. MIXED BREEDS COUNT TOO Most cats are wonderful mixes. CatDex says so honestly, logs them as Domestic Shorthair, Mediumhair or Longhair, and tells you which breeds they take after. COLLECT ALL 106 BREEDS From the everyday Maine Coon to the legendary Kellas Cat, every breed has a rarity: Common, Uncommon, Rare or Legendary. Rarer finds are worth more points. YOUR PHOTO JOURNAL Your own photo becomes the breed's card. Give each cat a name, jot down where you met, and look back on every sighting. DAILY BREED QUIZ Five new questions every day. Build a streak, share your score, and keep practicing as long as you like. BREED OF THE DAY Learn about a new breed every morning, with its history, personality, size and lifespan. BADGES & MILESTONES Earn badges for discoveries, rare finds, collecting breeds from around the world, and quiz streaks. Works offline for browsing. Your collection stays on your device.

Verdict

The call

The clearest difference is price: QR Code vCard at Free against CatDex's $1.99. QR Code vCard also leads on ratings volume (20 vs 1). CatDex's advantage is rating (5.0 vs 4.4) and update cadence (every 3 weeks vs every 5 months). On ads, in-app purchases and device support there is nothing between them.
