About
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. As the last line closes the frame, the card fades in inside it — the exact card you intended, every time. No switching apps, no buttons, no gimmick in sight. Just a finger and a screen your spectator has been watching the whole time.
FOUR WAYS IN
Show — a bare canvas. No prompts, no guides, no tells. The only thing on screen is what you draw.
Practice — the same canvas with on-screen guides and hints while you learn the system.
Trainer — the app names a card, you draw it from memory, and it grades the attempt. Drill until it's automatic.
Cheat Sheet — the complete mapping on one screen, for study between shows.
BUILT FOR PERFORMING
• All 52 cards. Nothing is off the table.
• The frame works anywhere on screen, at any size, drawn with any finger.
• Haptics confirm each edge silently, so you never look down to check.
• Nothing ever appears on screen that a spectator shouldn't see.
THE METHOD
The card is encoded in how you draw the frame, not in what you draw. Anyone watching sees a rectangle. You know the difference. It takes an evening to learn and about a week to make invisible.
PRIVACY
No account. No sign-up. No network. No data collected, ever. Card Sketch works entirely offline — on airplane mode, in a basement, in the back of a cab.
Card Sketch is a tool for performers. It won't do the work for you. What it gives you is a clean, silent, always-ready reveal that lives in a pocket you were already carrying.
