First, LOVE the video tutorial that walked me through the steps of the app, very helpful, bright colors, reward/earning puzzle peices, great incentive to finish lesson, love being able to make choices of which applications we can use or want to use, my child is RTS 12 years old at a K level and non verbal, at first I thought he won't be able to use this app, TO my surprise he can thanks to the color coded sentence lines and sentences, love that we also have the option of turning those off at some point to see if he really understand the sentence or not. Love the record option although we can't use it, but can turn it off and making button options at the end of the sentence placement easier for him. Love the save option and email option also. Overall, we love the app and can't see anything to improve on. thank you
