In the application's configuration options you can select the color that you want to illuminate the screen as well as the sound that you want to begin hearing little by little. Of course, you will also choose the time of day and which days the alarm will go off.
Another option available with Smart Gentle Alarm is to add vibration to the sound and light. This way, as time passes, not only will the volume increase and the light get brighter, but your device will begin to vibrate as well.
Smart Gentle Alarm is a complete application that will help you wake up without any problems. With this app installed, you can forget about any more rude awakenings.
