I recently released a cool math app for kids (Ages 6-11) in the Android platform.
Spooky Math takes kids on exciting adventures across magical farms, wild jungles and spooky mountains where they solve real world Math problems that show up along the way. Combined with exciting rewards, thousands of practice questions and a mental math section that shows how to mentally calculate numbers in a matter of seconds, this app is sure to keep children excited and motivated.
Since I can't post a link here, please do look up "Spooky Math" on Playstore and let me have your feedback.
Many Thanks -
