Mark is one of nine children. His parents are a Stanford-educated rocket scientist and classics scholar. They taught him math and reading when he was very young, for which is still very grateful. Thanks, Mom and Dad. I would not be here without you.

Mark remembers enjoying a game on the computer called 'Math Blaster' which he liked primarily because of the sound effects and graphics. He is excited about the potential of apps to give great educational experiences to kids of all backgrounds.

Mark has a B.S. degree in Computer Science, Math, and Applied Physics from Xavier University, and an M.S. degree in Computer Science from the University of North Carolina.


Christine grew up in Guangzhou, China. When she was in high school, she kept a book where she wrote down the mistakes she made. Every time she made a mistake, she'd add an entry in that little book. This led to her becoming a thorough and diligent person.

In addition to being consistent, Christine is also a font of creative joy. Professor Tomato is based upon one of the many fanciful characters Christine has invented to give color to our live together.

Christine has a B.S. degree in Computer Science from Peking University and an M.S. degree in Computer Science from the University of North Carolina.

  • My kid has a lot of fun with it! My toddler is always trying to get grab my phone. There isn't really anything for him to do on there, though, other than mess stuff up. This fun little game is just right for him (he's 2). It keeps him occupied while we cook dinner, etc.

  • You can count on this app. This is the best counting game I own. It features peaceful music, fun sounds, and vivid colors. I'm looking forward to more from Professor Tomato.

  • Simplicity for Learning. Without the crazy distractions that other apps seem to have this is by far the best counting app I have seen. I will probably will never need to download another counting app again.
