Free. Voo is Cardvoo's index-card mascot. Study to earn skins and accessories, all free.
Say hi. Voo shows up around the app with short tips. You can switch tips off any time. Earn things. Streaks, wins and mastered cards unlock skins and accessories. A 7-day streak earns the Sky skin. Winning 5 games earns Headphones. Dress up. Pick a skin plus a head, face, neck and held item in Settings. Every cosmetic is free. There's nothing to buy. Once earned, an item is yours to keep even if your streak drops later. Unlocks are worked out on our server, so they can't be faked. New accounts start with the Teal skin and a grad cap. Turn off Voo animations in Settings and Voo stays still.
