4. Sleep As Android
Sleep as Android is an alarm clock developed by Urbandroid Team. Sleep as Android will track your sleep and will choose the best moment to wake you up. Set up alarms by typing, text-to-speech, or with a wheel control. Choose from multiple repeating alarms and wake up to your favorite music. The alarm won’t stop until you scan a QR code in your bathroom. Shake your device to stop the alarm. You can download Sleep as Android from the Google Play Store here.
