Unleash the Power of Mentalism Phonewords lets you connect with your audience on a whole new level — revealing secret thoughts like names, words, numbers, places, or even birthdays. With just a birth date, you can reveal how many days they’ve been alive, the day of the week they were born, or even a celebrity who shares the same day and month. You can also subtly influence decisions — forcing specific numbers without them ever realizing it.
 Seamlessly integrating with your phone's dial pad, Phonewords decodes hidden words, revealing the thoughts they NEVER wrote down. The app's interface and intuitive design makes it a workable tool for live performances or pre-show. Seamless Integrations: • GLYPHS • LUMEN EYE • INJECT • GOO • SB WATCH • PEEKSMITH • APPLE WATCH • API / URL SCHEMES • KEYBOARD REMOTES • EARPIECE AUDIO DEVICES
 Just Some of the Features That Hit Hard • HEIGHTEN YOUR SENSES: Create the illusion of perfect pitch — even blindfolded, you reveal the number they dialed by recognizing the subtle tones of each key. • MIND READING: They never typed it. They never wrote it. Yet from thousands of possibilities, you reveal exactly what they were thinking. • IN SYNC: You and your spectator move in perfect harmony. It’ll feel like they’re reading your mind. • INFLUENCE: They think it was their choice. You prove it was yours all along. • ACROSTIC REVEAL: They think of any name — completely their choice. But when you reveal your list, they discover something impossible: every name on it begins with a letter from the one they merely thought of… acrostic style. A perfect illusion of free will, expertly guided from the start. • CONTACTS PEEK: Let them search any contact on your phone — and you instantly know who it is. Works with PeekSmith, Glyphs, audio peek, or via URL Scheme, API, or Portal to your favorite app. • BUT WAIT....THERE'S MORE ;) Multilingual Friendly: While the app menu and settings are in English, Phonewords supports performance using in other languages.
 IMPORTANT NOTE: Video and audio broadcast rights (TV, film, radio, internet) are not included. This app is licensed for live performance only. DISCLAIMER: Phonewords is for entertainment purposes only. It won’t give you real psychic powers or make you a wizard… unfortunately.
