1s are confusing – 1 to 100 - Help your kids learn to count to 100, one number at a time! Review

The app works well but is confusing to my son because the ones are not clear -- they look a lot like a seven. He is also not familiar with seeing 7s with the cross bar. We would love the app if the numbers were easier to read and understand.
