Fun app to learn number sequence

The children in my class really like this app.
I see this app as a great way to learn number and number sequence.
The app has some customizable features with numbers and with different languages as well.
I see this app as a great way to teach and reinforce couting up to twenty, especially the teens, where young children can get mixed up quite easily.
This app is a variation on connect the dots.
The app speaks the numbers in sequence as the child connects the stars.
