Dusk Scout

Dusk Scout helps you find the perfect time to fall asleep based on natural sleep cycles.

Your body moves through 90-minute sleep cycles throughout the night. Waking up in the middle of a cycle leaves you groggy and tired — but waking up at the end of a cycle feels natural and refreshing. Dusk Scout calculates exactly when you need to fall asleep to wake up at your target time, aligned with your cycles.

Enter your desired wake-up time and instantly see three options: 4 cycles (6 hours), 5 cycles (7.5 hours), and 6 cycles (9 hours). The app highlights the sweet spot — the window closest to the recommended 7.5 hours — so you can make the best choice for any night.

Save your most-used wake times as presets. Set up a "Workday" preset for 7:00 AM and a "Weekend" preset for 9:00 AM, then switch between them with a single tap.

Track your sleep every day with the built-in sleep log. Log your actual sleep and wake times, rate your sleep quality, and add a quick note. Watch your streak grow as you build a consistent routine. After a week, Dusk Scout shows you insights — your average sleep duration, which days you rest best, and your consistency score.

Fine-tune the calculator for your body: adjust the cycle length (80 to 110 minutes) and the average time you take to fall asleep. Every person is different, and Dusk Scout adapts to you.

Simple, fast, and distraction-free. No accounts. No subscriptions. Everything stays on your devic
