My three year old daughter has been playing with ABC magnets on our fridge. One day she wanted to spell DADDY. She could not because we had only one set. I made this app for her to be able to spell anything she wanted to. Fast forward three years, she now reads at the third grade level. She is way past the age to use this app. I keep this app up and running for other parents.
