SAY, “Why the name Clementine in the movie Eternal Sunshine?”, then “Explain the meaning of the ending scene.”

ALWAYS-ON screen and horizontal display as presentation modes. Use this app along your car like an audio dashboard during commute, or next to your laptop like a sidekick during work. So, mostly screen-free and hands-free!
