## What is Circadian Rhythm?

Start fresh. Well rested. Every single day.

DawnPal is a sunrise alarm clock that wakes you with the sun — so you begin each morning with natural energy instead of fighting your body clock.

WAKE UP AT SUNRISE
Your alarm follows the sun. DawnPal detects your location and wakes you at the exact moment of sunrise — earlier in summer, later in winter. No more guessing, no more darkness.

SLEEP YOUR FULL NIGHT
DawnPal counts back from tomorrow's sunrise using your sleep duration to find your ideal bedtime. A gentle nudge tells you when it's time to rest — so you wake up refreshed, not groggy.

GRAB ALL THE DAYLIGHT YOU CAN GET
See how much sunlight your day holds. Sunrise, sunset, and total daylight hours — at a glance. Make the most of every bright hour.

A HEALTHIER, MORE NATURAL LIFE
Our bodies run on a circadian rhythm synced to sunlight. When you align your sleep to the sun, everything shifts:
• You fall asleep easier
• You wake up with calm, natural energy
• You feel more alert and focused
• Your mood lifts
• You start living with the day, not against it

FEATURES
• Sunrise alarm — wakes you when the sun rises
• Smart bedtime — counts back from sunrise + your sleep need
• Works anywhere — updates automatically as you travel
• Shift alarm — offset your wake time from sunrise
• Sleep duration — set your personal sleep need
• Beautiful backgrounds — customize from your camera roll

DawnPal is the simplest way to align with the natural cycle of the sun.

### 5/5 — Slept Better last night

*2025-03-25*

Using the app, I slept better last night. thanks for helping me

### 1/5 — Not as advertised

*2025-01-16*

I downloaded the circadian life app but what is now on my phone says Dawn app.  It doesn’t show anything about maximum UVB hours.  I feel deceived.

**Developer response:** Hi, I'm sorry that you did not get what you expected. I'm not sure where the information comes from, that the app provides UV-B hours? Was that an ad probably? I never promised this in the Appstore information, or the App - something went wrong here. Please contact me using "Bugs and feature requests" in the Settings menu. Best, Ingo

### 5/5 — awsome

*2024-10-11*

One of the best apps
