How much time have you spent outside today?
HelloSun turns your time outdoors into something you can actually see — right on your Apple Watch and iPhone.
Your day starts in darkness. Every minute you spend outside makes the sky brighter, until the sun is shining and your daily goal is reached.
SEE YOUR DAYLIGHT AT A GLANCE
Your Apple Watch already tracks the time you spend outside. HelloSun turns that data into a simple, visual daily goal.
FROM NIGHT TO DAY
No complicated charts. Your progress is represented as the time of day. The closer you get to your goal, the brighter it becomes.
MADE FOR APPLE WATCH
The standalone Watch app runs right on your wrist. Your iPhone can stay at home.
YOUR SUNLIGHT BUDGET
See how much daylight you've already had and how much is left to reach your daily goal.
SUNSHINE, WITHOUT THE SUNBURN
HelloSun combines the live UV index, your skin type and the sunlight you've already had to give you an easy-to-understand estimate for the day. HelloSun is not a medical device.
WIDGETS & COMPLICATIONS
Keep your daylight progress where you can see it — on your Home Screen, Lock Screen and watch face.
YOUR DATA STAYS YOURS
Daylight data is processed on your iPhone and Apple Watch. No account. No server. No uploads. No ads. No trackers.
STREAKS, RECORDS & HISTORY
See your streaks, discover your best days and look back at your progress over time.
Going outside doesn't have to be complicated.
HelloSun. Get your daylight.
