Has potential
This app has lots of potential - I hope the developers will continue to work on it. I agree with the only other reviewer so far that the order the words are presented in needs some randomization - I often grab a couple of minutes between other activities to work with an individual student and the app will not be as useful if they start with the same words every time. I've only used it with one student so far and he enjoyed it, though he often picked the correct letter and then had difficulty dropping it in the right place so the tracking report shows more errors than he actually made.
