Set the alarm time in just two seconds. This simple alarm clock app has been designed for maximum ease of use. Set your favorite music as your alarm and wake up happy! ALARM FUNCTIONS: - Snooze (3 - 30 minutes) - Vibration - Fade in alarm OTHER FEATURES: - Sleep timer (sleep music) - 12 hour and 24 hour time format - Vertical and horizontal modes MORNING: Use music of your choice or select one of the preset alarms to wake up happy and smiling. EVENING: Relax and fall asleep to the sound of your favorite song or one of the preset sleep music. APP FEATURES: Unique and intuitive interface is easy to use: launch the app and have your alarm ready in just two seconds. WHY WE DEVELOPED THIS APP: There are many alarm clock apps found on the App Store today. However, most of these require the user to tap through numerous screens just to set an alarm. Also, most of these apps use a built-in widget for the interface, making it hard to interact with them intuitively. If you find yourself regularly changing your alarm time, the existing apps out there are a real pain. That's why we developed this new app, which uses an analog clock for inspiration.
