Pi Cue is a professional performance assistant for magicians, mentalists, memory performers, and live interactive demonstrations. The app helps performers work with number-based routines built around the digits of pi. A spectator can name a 4 or 5 digit number, and the performer can quickly find where that sequence begins within the first million digits of pi. Pi Cue is designed for rehearsal, preparation, and live performance support. It keeps the technical process simple, quiet, and organized, so the performer can focus on presentation, timing, and audience interaction. Key features: Pi Position Search Enter any 4 or 5 digit sequence and instantly find its position inside the first million digits of pi. Remote Keyboard Support Use an external keyboard or remote input device to type digits during performance. Full-Screen Wallpaper Mode Prepare a custom full-screen performance layout that can blend naturally into a live environment. Receiver Support Send the found position to a compatible receiver when available, allowing cue information to stay clean and unobtrusive. Edit Mode Adjust the layout, result text, clock display, peek marker, opacity, background style, and positioning for your preferred performance setup.

Pi Cue is suitable for: Memory demonstrations Pi memorization routines Mentalism performances Number prediction effects Close-up magic Salon performances Private shows Rehearsal and routine design Before using Pi Cue in a live performance, complete a full setup rehearsal. Confirm your input method, wallpaper layout, receiver settings, and cue display before performing for an audience. Pi Cue is intended for professional performance use. It does not replace the performer’s script, timing, personality, or presentation skills. Instead, it helps keep the technical structure clean and dependable, so the performer can focus on the audience, the story, and the moment of impossibility.
