Here’s a little app you mightn’t have heard about!
PracTime is an app to help students and musicians track their practising and performing. In addition to showing graphs of practice time, students can see what their friends are practising by linking through with Facebook. Students can also easily share their accomplishments with their friends or teachers by e-mail.
I’ve played around with this app for a few weeks and have a feeling it might really capture those teens who enjoy to ‘compete’ with their mates in regard to the amount of practice they are doing! I think that linking with Facebook will be an instant hit too given how much time everyone spends on it these days.
Oh, and it’s free 
Sounds great! Thanks for the suggestion. My teens are so busy. I don’t know how they find time to practice.
