As a special education, I love this app! As a math tutor, I love this app! As an individual I love this app! Honestly, I helped my wife understand math better when she was trying to complete a college math course. This app is great for ages 5 and up. The DragonBox Algebra 12+ is great for ages 12 & up. I own both & use both. I bought 12+ from the Google Play Store though.
