# Card Sketch > Card Sketch is a card reveal app for iPhone and iPad, made for close-up card magic. The performer draws a small rectangular frame on a blank screen with one finger, and as the last line closes the frame, the spectator’s chosen card fades in inside it. Any of the 52 cards can be revealed. The app works fully offline, needs no account, collects no data, and shows nothing on screen during a performance except what the performer draws. It includes Show, Practice, Trainer, and Cheat Sheet modes and is available in English and Spanish.

The spectator has a card in mind, or has chosen one by any method the performer likes (a force, a memorized deck, a peek). The performer opens what looks like a plain drawing pad on their phone and doodles a small rectangle with one finger. As the fourth line closes the rectangle, the chosen card fades in inside the frame. - Any of the 52 cards can be revealed, chosen on the fly while drawing. No preset list. - The frame works at any size, anywhere on the screen, with any finger. - Nothing appears on screen during a performance except what the performer draws. No buttons, guides, or error messages. - The card is decided by a method the performer learns and carries in their head. The app never displays the method during a show. - Watching the performance reveals nothing. Knowing the app exists is not the same as knowing what the performer did. ## Modes - Show: bare canvas for performing. Only the performer's strokes are visible. - Practice: the same canvas with guides and hints on, for learning the method. - Trainer: the app names a card, the performer draws it from memory, and the app grades the attempt and tracks a streak. - Cheat Sheet: the complete method reference on one screen, kept behind Settings. ## Performer features - Haptic confirmation: a silent tap confirms each edge, so the performer never looks down. - Optional soft card sound on the reveal, or complete silence. - Arm a card ahead: set a card from a hidden control before handing the phone over. It fires once, then clears itself. - Learning time: roughly one evening to understand the method, about a week of Trainer to make it automatic. ## Privacy Card Sketch makes no network requests and works entirely offline. There is no account, sign-up, analytics SDK, advertising SDK, or third-party tracking. Settings and Trainer scores are stored locally on the device only. ## Pages - [Home](https://cardsketch.com/): overview, modes, screenshots, features, FAQ. - [Support](https://cardsketch.com/support): contact and common questions. - [Privacy Policy](https://cardsketch.com/privacy): no data collected. - [Blog](https://cardsketch.com/blog): articles on card reveals, forces, memorized decks, and phone magic. - [Inicio en español](https://cardsketch.com/es): Spanish version of the home page. - [Soporte](https://cardsketch.com/es/soporte): Spanish support page. - [Política de privacidad](https://cardsketch.com/es/privacidad): Spanish privacy policy. - [RSS feed](https://cardsketch.com/rss.xml) - [Sitemap](https://cardsketch.com/sitemap-index.xml) ## Blog posts - [How to Force a Card: A Practical Guide to the Most Useful Skill in Card Magic](https://cardsketch.com/blog/how-to-force-a-card): What a card force is, the classic forces every performer should know — cross-cut, riffle, classic, and psychological — and how a reliable force unlocks any reveal you can imagine. - [Card Reveal Techniques That Audiences Actually Remember](https://cardsketch.com/blog/card-reveal-techniques): From classic productions to impossible locations to drawn and digital reveals — a tour of the ways magicians reveal a chosen card, and what makes a reveal land. - [Drawing Reveals in Magic: Why a Sketch Beats a Deck of Cards](https://cardsketch.com/blog/drawing-reveals-in-magic): The history and psychology of the drawing reveal — from mentalism's drawing duplications to modern sketch reveals — and why a hand-drawn image is one of the strongest ways to reveal a card. - [Performing Magic With Your Phone (Without It Looking Like an App)](https://cardsketch.com/blog/phone-magic-that-fools): Why most phone magic fails, the design and performance principles that make digital effects fool people, and how to handle the inevitable 'it's an app' suspicion. - [Memorized Decks and the Art of the Reveal: A Perfect Pairing](https://cardsketch.com/blog/memorized-deck-reveals): How a memorized deck like Mnemonica turns free selections into known cards — and why pairing stack work with a strong visual reveal builds the cleanest card magic there is. ## Related - [Mnemonica — Stack Trainer](https://mnemonica.app): companion iOS app by the same maker for learning memorized decks (Tamariz's Mnemonica, Aronson, or a custom stack), with ACAAN training.
