Convenient Clock is a small, fast and free alarm clock. Plays MP3, MP2, MP1, OGG and WAV sound files, and has a beep alarm function for computers without a sound card. Convenient Clock can also run a program at alarm and display a custom reminder message. Minimizes itself to the system tray and supports both 24-hour and AM/PM time formats. Also has an egg timer feature for shorter-term alarms. Waking up to MP3s has never been this convenient!
