This app is great for building vocabulary in children ages 20 months and above. My 20 month-old son is able to use the app with little assistance and my special needs students (ages 3 - 8) also enjoy building scenes and playing the mini-games at the end. The music, sound-effects, and naming of pictures can be a bit intense for some. I will either turn the volume way down, or mute it altogether.
Overall, I have found this app useful in therapy. I am able to target vocabulary development in themes (e.g., farm animals, jungle animals, etc), spatial concepts (e.g., The bee is on the flower, The cow is behind the barn), and sentence structures (e.g., The girl is throwing a snowball). Overall, a B+.
