Sunn is an app to help you get a better nights 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.

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 bodys nighttime production of melatonin.

Pros and cons of Sunn - Circadian Lighting for Philips Hue app for iPhone and iPad

Sunn - Circadian Lighting for Philips Hue app good for

I dont usually write reviews, but those 1 star reviewers obviously did not understand what this app does. It does exactly what it does, which is to match the color of your hue bulbs to the sun. Would recommend.
Best part about this app is that it works! It actually changes the lights throughout the day and is very comfortable to sit, relax, and listen to my klipsch speakers in this light. Easy to use too, people who didnt understand this app probably quit after about 5 minutes so makes sense why they wouldnt get it :/

Some bad moments

You need to open the app regularly (multiple times per day), otherwise the lights are not updated.
I really love the idea of this app. Unfortunately it does not work as supposed. I use it together with my Philips Hue-System. Pairing works flawlessly and if you open the app it indeed sets the color-temperature of your bulbs according to the local sun position. BUT the Background-Sync Option has no effect, so the lights are not updated when you dont leave the app open and active. Without this functionality, in my opinion the core feature of such an app, this app is nearly useless. Id love to see an update on that.
Awesome idea, but the app doesnt run in the background. In other words, unless you consistently re-open the application, the lights will remain static and defeats the point of the entire application.
Gave it a 5 stars before. Please update it.. Now doesnt connect to Hue hub
This app cannot even find the lights. The. Implant says they are aware of the problem and have made the app available for free while they try to fix it. Yay. An app that doesnt work and takes up space on my phone. Forget this app as the company has had ample time to figure it out. Pass
No matter what I do this app will not allow me to connect with my Hue Bridge. So when I try to connect my Hue lights via the Connect Lights setting, I press the Hue Lights button then it asks me to press the Hue Bridge button and the prompts with a popup, so I press my Hue Bridge button then press OK on the app and it just dismisses the Hue Bridge each time which doesnt allow me to connect with the bridge. Ive also tried to press the hue bridge button without pressing the OK button on the app and it still doesnt connect (no matter what order or how I try to do it). So until the developer fixes this, the app is useless until I can connect my lights.
