We are currently working on a system which will allow for student accounts to be accessed on multiple iPads. What this will mean is that if parents have the app on their home iPad, and the teacher has the app on their iPad at school, they can each access the student's account with saved settings and progress-report information. That way everyone working with the student will be working on the same lessons, and building on the student's existing progress. In addition, we will offer a web portal where parents and teachers can access information on the students work, and share notes on other aspects of the student's educational program.
We expect this feature to be available in mid 2016.
