About

Rouge Pro

Read full description

Rouge Pro is the digital evolution of nail writing, one of mentalism’s most closely guarded techniques. The psychology at its core is simple and unassailable, and Rouge Pro applies it to the smartphone already in your pocket. In an innocent looking note-taking and drawing app, you sketch basic images, shapes or symbols for your participant to choose from. You explain that you will circle the one you believe they will choose. The prediction is made, and cannot be changed, or so it seems. Once your participant tells you their choice, Rouge Pro’s secret method allows you to alter the prediction invisibly, so that when you show them your screen, it looks as though you knew all along. Rouge Pro allows you to make text predictions too. For example, you write a list of all twelve star signs and explain that you will put an emoji next to the sign you believe your participant is. The prediction is made, and when they tell you their sign, you quietly shift the emoji’s position, landing it next to the correct one. Your participant does not see the process, only the result, which is always correct. As well as lists, Rouge Pro can change predictions in single lines of text. Instead of listing every star sign, you simply write one: the sign you believe is theirs. Your prediction is made, and by the time you are ready to show the screen, it appears correct. Rouge Pro also allows you to force words, items, names, places and more. List the items from one to six, or more if desired, and ask your participant to imagine rolling a die. Whatever number they say it landed on will match the item on your list that you wish to force, thanks to Rouge Pro’s secret method. Finally, Rouge Pro offers a peek feature, so your phone can be handed to a participant while they write something: a thought, a place, a date, a name, or anything else you choose. They then lock the device and hand it back to you. Without unlocking the phone, you know what was written. Multiple methods are included, with optional Flic button support for a totally hands-off process. This is not a note-taking app, drawing app or productivity tool, it is simply designed to look like one. Rouge Pro is a specialist performance instrument for magicians, mentalists and mystery performers. Built for impossible predictions. Designed to look ordinary. Made for workers. Please note: Rouge Pro is an entertainment app, and while designed to create the illusion of psychic ability, it cannot grant genuine psychic powers.
