To turn off the alarm, you read your affirmation out loud. There is no snooze button. The moment you speak, the sleep breaks. And the direction of your day is set. No math problems. No shaking your phone. RYZA turns those few seconds into the actual start of your day. Read to Wake™ When the alarm goes off, the affirmation you chose appears on screen. You read it out loud, your speech is recognized, and the alarm stops. "I start before I feel ready." "Today I am one step ahead of who I was yesterday." A promise to yourself, today's goal, or a line you want to keep in mind. It works with a morning voice Don't worry about being too hoarse to be understood. If recognition struggles, the app switches to putting the words of your affirmation back in order. The alarm never turns itself off, and you never get stuck unable to turn it off.
