Card Sketch

Card magic you draw by hand. Sketch the outline of a card on a blank screen and it fades in inside the frame — the exact card you intended, every time.

For iPhone and iPad · All 52 cards · Works fully offline · In English and Spanish

  • An ace of diamonds revealed inside a hand-drawn frame
  • A half-drawn frame on the blank Show-mode canvas
  • Trainer mode marking a six of diamonds drawn from memory as correct

Card Sketch turns your phone into a drawing pad that already knows the card. You sketch the outline of a playing card on a blank screen and, as the last line closes the frame, the card fades in inside it. No switching apps, no buttons, no gimmick in sight.

The card is encoded in how you draw the frame, not in what you draw: anyone watching sees a rectangle. All 52 cards are available, the frame works anywhere on screen at any size, haptics confirm each edge silently, and nothing ever appears on screen that a spectator shouldn’t see.

Four modes cover the whole journey: Show, a bare canvas with no tells; Practice, the same canvas with guides while you learn; Trainer, which names a card and grades your attempt; and a cheat sheet for study between shows. An app by Sinfonika, built in collaboration with Cantain.
