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. Free from day one • Unlimited standard alarms • 1 Read to Wake alarm, dismissed by speaking • 120 original affirmations across 6 categories • Home screen widget with today's line • A fixed affirmation, or a new one daily • Your daily wake-up result • Light and dark mode • English, Korean, Japanese, Spanish, French RYZA Premium • Unlimited Read to Wake alarms • Voice verification on every alarm • 600 affirmations across 9 categories • Premium packs: fitness, business, discipline • Write your own affirmations • Wake Up Check: confirms you didn't fall back asleep • Stats: 7-day success rate, average time to dismiss, streaks • Separate setups for weekdays, workouts, study, weekends Start with a 3-day free trial.

Dismissing an alarm takes a few seconds. Those seconds add up. Tomorrow is coming either way. How it starts is up to you.
