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.

LetterRack. The Mentalist's Secret Weapon. Mentalism lives on one thing: focus. LetterRack gives your spectator exactly what their mind needs to lock onto a thought. Three powerful effects, one elegant tool: A spectator thinks of a random word generated by the app. The mentalist reads their mind. A spectator unscrambles an anagram and focuses on the hidden word. The mentalist reads their mind. A spectator freely chooses any word. The mentalist reads their mind. Three different paths. One impossible outcome. Full control for the performer: LetterRack gives mentalists full control over their letter sets, preparing, organizing, customizing, and cycling through words with precision, so the performer can focus entirely on the audience, not the mechanics. Instant sharing, zero friction: Generate a QR code in seconds and let your spectator scan it with their iPhone. No app download required. They land directly via App Clip, turning their own phone into part of the effect. Always within reach: A Home Screen widget keeps your current word visible at a glance, ready the moment you need it. They think it. You know it. Word lists currently available in English only. Additional languages coming in future updates. The app is free to download and try with up to 5 words. The widget and Apple Watch complication are free to install but show only the first letter of the word. Full word display, App Clip, custom word lists, and advanced word management require an Xtremagic Pass subscription or one-time purchase.
