## What is Sunrise Simulator?

Sunrise Simulator allows you to control LIFX and Hue lights as a sunrise alarm clock. You can choose the duration of the sunrise and your desired wakeup time. During the sunrise the app will gradually brighten the lights and increase the color temperature from warm to cool.

If you haven't woken up by your set time, the app will play a sound you have chosen.

You can control multiple lights from different manufacturers at the same time. 

You must have a smart lightbulb for the sunrise simulator to be fully functional. If you are in a location without a smart bulb, you can use the phone torch to simulate the sunrise. To do this, you MUST NOT lock your phone. 

If you do not any smart bulbs you can use the app as an audible alarm.

The audible alarm can be any sound from your playlist, or you can choose from a variety of natural sounds such as waves, rain or bird calls. If you are a heavy sleeper you can also choose a siren. The siren setting will also strobe the light after the sunrise if you haven't cancelled the alarm.

You can also use the app as a night clock as long as you do not lock your phone. You can adjust the brightness of the display by dragging your finger up or down on the screen.

Version 3 supports multiple locations, so you can have different setups for different houses. The app will attempt to determine the location automatically, but you can also set the location manually.

### 1/5 — Confusing app

*2024-07-23*

Thus app is NOT user friendly. It seems so simple, but it is totally confusing. It has no instructions or directions. I would like a refund, please!

### 1/5 — Needs more work

*2018-12-25*

Not user friendly. Possibly make a YouTube visual manual to show how it works?

### 1/5 — Not A Good Choice

*2018-12-12*

The interface is confusing and never seems to work properly. There’s not a lot of customization, from what I understand if it. It keeps popping up weird notifications that seem to make no sense. I’m sorry, but I can’t recommend this app. I’d like a refund.

### 1/5 — Nothing worked,wish I could get my money back

*2017-02-17*

Doesn't work

### 2/5 — Bugs

*2017-02-12*

Can't create token or authorise app, just loads a webpage from Lifx that shows pre authorised apps. Eager to try once fixed.

### 5/5 — I really like this app!

*2016-10-18*

I have used this app for over a month and I am very satisfied.  When I email’d a clarification question about app operation, the developer was very responsive.  Over the years, I have tried various physical sunrise clocks to wake during this time of year when it’s dark in Colorado at 6am.  Even with the cost of the LIFX bulb, this solution is by far the easiest to use and most cost-effective.  I highly recommend this application.
