The first important thing about Sunrise Calendar is that it allows you to synchronize the app with Google Calendar, so any dates that you had set by default in your Android device (birthdays, alarms, etc.) will automatically appear in Sunrise Calendar.
The best thing about Sunrise Calendar, however, isn't the fact that it synchronizes with your Google Calendar account or that it includes tons of possibilities when it comes to scheduling your appointments. It's the fact that it allows you to personalize them and give your device a touch of something different.
You can establish different colors, select different icons, tag your contacts, and much more, all with the goal of making your alerts more recognizable and intuitive.
Sunrise Calendar is a simple, elegant and powerful calendar for Android that allows you to keep track of all of your appointments and alerts.
Requires Android 4.0 or later.
