Math Kid Genius-math for kids

I develop this app for my kids to learn math at fast speed & hope that other kids will get the same benefit. This app has addition & subtraction, which are fit for preschool to elementary school levels. Students can adjust their own timer according to their learning pace. Parents can also set up ranges of numbers that they want for kids to work with. This app is created as an ALL-INCLUSIVE app, which means you will get all the features of addition & subtraction math apps. You only need to buy 1 app & you are done! Truthfully, 50% of your support proceeds on this app will be donated to feed the poor & needy. Thank you for trying it out.
