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.
