I was looking for an app to help me take interval data for on task behavior at school. The app did not allow me to write in my own behavior for observation and none of the choices listed were positive alternative behaviors. The app also did not buzz or vibrate to alert me when the interval was up so that I could input the data, so I had to constantly keep checking the time. It was also expensive! I wish I could get my money back.
