"Hey Product Hunt! 👋
Built Sleepright because I kept waking up exhausted even after 8 hours. Turns out timing matters as much as duration — waking mid-cycle feels terrible. Sleepright calculates your ideal bedtime based on 90-minute sleep cycles so you always wake at the right moment.
What time do you need to wake up tomorrow? Drop it in the comments and I'll tell you when to go to bed! 😴"
