Sunn is an app to help you get a better night's sleep.
The Sunn app helps improve sleep at night and alertness during the day by keeping your body clock / circadian rhythm, in sync with nature. It does this by adjusting the color and brightness of indoor lights. The Sunn app automatically adjusts your lights to match your location, time of year and time of day to provide the right light at the right time.
THIS IS NOT A BLUE LIGHT FILTER APP. The Sunn app is designed for Philips Hue and Apple HomeKit smart lights. It adjusts the color or brightness of these lights. It does not adjust the color and brightness of your iPhone or iPad screen.

THE SUNN LIGHTING EXPERIENCE
In the morning, Sunn makes your lights rise with the sun, gradually brightening and changing color to foster wakefulness and assist your body’s natural suppression of melatonin. During the day, your lights track the sun and slowly become cooler to promote alertness. As the day winds down, your lights become warmer and bring the setting sun indoors. At night, the Sunn app slowly adjusts your lights to emanate the calming glow of firelight, a biological indicator that prepares you for rest and promotes your body's nighttime production of melatonin.

Ratings and Reviews
Doesn't work unless app is open
This app was a great idea. I was so excited for it because my grandmother has Alzheimer's and dementia and the research I have read said it was good to keep indoor lighting to the same lighting as the natural outdoors sun runs threw the day. That it would help with her mood and sleep dramatically.
However, I wasted my money in purchasing this app because it only works when it is opened up on your screen and running. It does not automatically continue to keep the same lighting as the sun gives....as the app said it would.
I would not waste your money. And I will never recommend this app as it does not do as it says it will do. That is false advertising. And against the law.
Works great for me!
Love this app! Another reviewer said that this app does not work when the app is not open on the phone. I’ve been using this for over a year and just wanted to mention that this is not the case for me on IPhone X and IPhone 7+ before that. This is the only app I know of that will keep my hue lights in sync with the sun, which really helps with circadian rhythms. Thanks to the developer and please keep updating!
Works, but app has to be running
I purchased this app so that my LIFX bulbs would follow the brightness and color of the sunlight outside. While this app does deliver that function, the app must be running for the bulbs to continue to update as the day progresses. Once I begin using another app, Sunn stops updating the brightness and color of my LIFX bulbs. Given that I don't want to have to run Sunn on screen for 24 hours a day, this app isn't useful.
Update - Feb 4, 2019: This app is basically unusable now. The time where I am located is 15:47 yet Sunn seems to think it’s 18:47. I’ve given Sunn location access, so I have no idea why it thinks I’m located on the east coast.
With Family Sharing set up, up to six family members can use this app.
