Rise & Shine: Smiling Alarm Clock is a free iPhone application developed by Thomas Fallon that aims to make waking up a more cheerful experience. The app requires users to smile genuinely to turn off the alarm, capturing the moment to share with friends later. It features multiple weekly repeating alarms, a dynamic interface that adjusts to the time of day, and a photo editor to fix morning bed head snapshots. Users can choose from a built-in alarm library or their iTunes music, add vibrate or strobe effects to alarms, and benefit from dark room mode that recognizes smiles. Additionally, the app suggests optimal sleep times for a well-rested awakening.
