Become Ambidextrous

Use this app daily to train yourself in ambidexterity. The app consists of a small game that challenges your left handed control and dexterity coupled with a small drawing/writing feature that challenges you to carry out daily tasks. Continuous practice in your pocket will help you to increase dexterity with both hands and enjoy the many benefits that come with that including better muscle definition and improved brain function.
While many brain training apps will claim to help your general IQ through tasks like maths, this is a proven way to improve general brain function AS WELL as your physical prowess, so give it a go!
