DAYZED - THE INSTANT DAY CALCULATOR Created by professional mentalist Paul Brook, Dayzed instantly calculates the day of the week for any spoken date. During performance, a spectator names any calendar date. The performer simply repeats that date into their own Apple Watch after starting a listening session. Dayzed instantly recognises the performer’s spoken date, calculates the correct day of the week, the iPhone then communicates the result through vibration, and displays it on the Apple Watch. Once activated, Dayzed can continue listening throughout your performance, allowing you to reveal multiple dates without stopping or restarting. It’s automatic, performance-focused, and designed to let you concentrate on your presentation. ------ SET IT AND FORGET IT Simply start listening and perform as you normally would. Dayzed works continuously throughout your performance, automatically recognising the performer’s spoken dates as they are repeated. Your iPhone can remain in your pocket, allowing you to focus entirely on your presentation while Dayzed quietly does the work. ------ BUILT FOR PERFORMANCE Dayzed is designed specifically for real-world performance. Choose how the app behaves with options including continuous listening, Blackout Mode, lock words, Apple Watch visual confirmation, and more. Every feature is designed to make Dayzed reliable, practical and effortless to use during live performance. ------ UNLOCK MORE WITH PRO FEATURES Enhance your performance with optional Pro features (In-App Purchases): API OUTPUT - send fully custom messages containing the detected date or day of the week to your own API endpoint URL OUTPUT - send fully custom messages containing the detected date or day of the week using your preferred URL Scheme CLIPBOARD OUTPUT - automatically copy fully custom messages containing the detected date or day of the week to your device’s clipboard VIBRATION CODE - create your own custom vibration patterns by assigning any combination of long and short vibrations to each day of the week ------ ALWAYS EVOLVING Dayzed is designed as a living performance tool for modern mentalists, continuously refined with new features, improvements and integrations.
