Dozy Sleep

Dozy turns the sleep data you're already tracking into something you can act on.

Most of us carry sleep debt without knowing how much. Dozy reads your sleep
from Apple Health, adds up the shortfall night after night, and shows you a
single honest number: how rested you actually are.

Then it does something about it. When you're running low, Dozy recommends a
nap, the right length, at the right time to help you catch up without
wrecking tonight's sleep. Finish a nap and Dozy logs it back to Apple Health,
so your recovery counts.

WHAT DOZY SHOWS YOU

Sleep Debt — your accumulated shortfall over the last two weeks, in plain
numbers. Tap any day to see exactly how you slept.
Nap Window — a personalized nap length based on how much rest you owe, grounded
in sleep science that favors short, effective naps.
Restorative Sleep — how much of last night was deep and REM, the stages that
actually repair you.

BUILT ON APPLE HEALTH

Dozy works with the sleep data your iPhone and Apple Watch already collect.
There's no extra tracking to set up, no account to feed, no servers. Every
calculation happens on your device.

A NAP TIMER THAT WAKES YOU GENTLY

Start a nap from your iPhone or Apple Watch. Dozy counts down and wakes you with
a gentle tap on the wrist, no jarring alarm, then credits the rest toward your
sleep debt.

PRIVATE BY DESIGN

Your health data never leaves your device for us. Dozy has no ads, no analytics
on your health data, and nothing to sell. What's yours stays yours.

Rest smarter. Nap on time. Wake up sharp.

Dozy requires access to Apple Health sleep data. Nap recovery estimates are for
general wellness and are not medical advice.
