I found this product to be very effective. It was very user friendly and engaging. The app itself ran very smoothly. I feel like the lessons/level progression was very solid and allowed you to move at your own pace.

My Take

I feel like this is an effective teaching tool because it allows the students to move at their own pace, and it is repetitive. The app also runs very smoothly and easy to use so it will not take long for the students to figure it out.
