This is a great app, but as others have noted, a few settings would make this perfect. For example, being able to set the time before the wake up time that the light starts to gradually fade in. And, the ability to adjust the volume of the birds from 0 to the lodest setting. Or, being able to set what color the fade in light starts at (such as a reddish or orange) and what color it is when it is fully on (such as white or yellow). Also, the screen needs to turn off completely during “sleep” so it is not using the LCD at all—turning off completely will reduce energy use and increase life of LCD display and prevent the dim glow from keeping light sleepers from getting to sleep or staying asleep.
Good app tho. I would pay for the additional features.
