Your bedtime,
calculated.
Not a fixed time. TuckIn calculates tonight's bedtime from your wake-up goal, today's strain, and your sleep debt — and shifts it automatically so you're always working toward full recovery.
Know what
you owe.
Two weeks of sleep debt tracked in one chart. The metric that tells you how tired you really are — spot the pattern, catch the debt before it compounds, and watch it shrink as the habit builds.
Today's strain.
Tonight's plan.
Worked harder than usual? You sleep earlier. TuckIn reads your Apple Watch data and shifts tonight's bedtime to match — automatically, every night.
What's breaking
your sleep?
Caffeine first. Alcohol and late meals coming soon. Log what you consume and TuckIn shows exactly how it's impacting your sleep — and learns what works for your body.
AI that never
leaves your phone.
All insights run on-device. No account. No cloud. No tracking. The model reading your sleep data lives on your phone — never leaves it.
