TuckIn: Sleep Schedule

Sleeping enough but still tired?

Most people don't have a sleep quantity problem — they have a sleep timing problem. Going to bed 30 minutes too late can cut your deep sleep in half. A hard workout day means your body needs a different bedtime than a rest day. And sleep debt accumulates silently — you stop noticing how tired you really are.

TuckIn fixes this.

HOW IT WORKS

TuckIn reads your health data and calculates a personalized bedtime every single night — not a fixed schedule, but one that responds to how you actually lived today.

1. Measures your daily strain — heart rate, active energy, workout intensity, and physical effort throughout the day
2. Tracks your sleep debt — how much recovery you've been carrying or missing over the past weeks
3. Understands your habits — logs factors like caffeine that shift your ideal sleep window
4. Sets tonight's bedtime — the exact time to go to sleep to wake up genuinely recovered
