A mentalism utility disguised as a personal astrology app. Zodiark is a secret tool for performers, a convincing astrology app designed to reveal star signs, offer short readings and create powerful moments of connection… all from your phone. To the casual observer, it looks like a personal horoscope app. But hidden beneath the surface is a secret functionality built for mentalists and magicians. With Zodiark, you can seamlessly guide someone through what feels like a genuine astrological experience, only to reveal knowledge you couldn’t possibly have known. In a unique twist, Zodiark also allows the audience member to become the reader, revealing the surrounding energy of the performer, in a beautiful take on the classic “spectator as mind reader” plot. - Reveal star signs with ease - Offer astrology-style readings with ease - Let participants reveal something about you Includes a link to a full video tutorial No internet required to use Zodiark, it works 100% offline No reset, no accounts, no learning curve Designed to feel organic and modern, Zodiark blends into real life and lets you perform anytime, anywhere, whether in casual moments or as part of a deeper theatrical piece. Optional Accessory: Supports integration with the PeekSmith wireless display for enhanced experiences. PeekSmith is not required for use. Important: Zodiark is intended for entertainment purposes only. It does not grant psychic ability or provide real astrological insight.
