Piano Phone Challenge

Students are starting to get APPS on their piano phones now. It's fun to see them get colorful. Only one week left until a winner is declared.  APPS have been given for 9 days in a row of practice. I thought that would be the last one to go up but it was one of the first. Family mini recitals, memory, and composition are some of the other APPs given this week. I wonder who the winner will be?
