Are you in search of an innovative way to sharpen your child’s reasoning skills and awaken their intelligence? Then you’ll love Busy Shapes designed for children from 2 years old! *** Featured in App Store Best of 2014 *** *** Featured worldwide by App Store as a Best New App *** *** Featured in the USA Today *** *** Recommended by The Good App Guide *** *** Common Sense Media Editors' Pick 2014 *** *** Parents‘ Choice Awards 2014 *** *** Children's Technology Review Awards 2014 *** > Inspired by the pioneering works of famed Swiss scientist and intelligence expert Jean Piaget (1896-1980) > Helps children improve their ability to handle simple objects through a series of engaging puzzles > Real-time dashboard to monitor progress > Includes an array of kid-friendly features, such as “passing” swipe control & more! ABOUT BUSY SHAPES Busy Shapes helps children improve their ability to handle simple objects through a series of puzzles, in which they must change simple shapes and place them in proper holes. Along the way, the app responds to each child’s actions with positive guidance and motivation. Plus, the app’s digital exploratory playground regularly refreshes with different objects, which keeps children interested and engaged. INSPIRED BY JEAN PIAGET Busy Shapes is inspired by the pioneering works of famed Swiss scientist and intelligence expert Jean Piaget (1896-1980), who believed that “children are little scientists”, and that a child's thoughts are built through experiences that encourage him or her to engage in the reasoning process. INNOVATIVE, SCALEABLE PLATFORM Busy Shapes’ innovative scaleable platform for evolving experimentation lets children take advantage of the time they spend on touch screens -- so they aren’t just having fun, but learning every second of the way. KID-FRIENDLY DESIGN Busy Shapes features a special “kid-friendly” design that compensates for the fact that when young children hold an iPad or iPhone, they often have a finger touching the screen. “PASSING” SWIPE CONTROL Busy Shapes features “passing” swipe control that is essential for young children's quick hands (i.e. even if a child's finger reaches an object after he or she was already touching the screen, the object is still grasped as intended). POWERFUL ARTIFICIAL INTELLIGENCE (AI) Busy Shapes’ powerful AI supports each child’s unique learning journey. For example, the AI tracks the time it takes each child to complete a level, and increases or decreases difficulty accordingly. GUIDED ACCESS To prevent children from exiting the app by pressing the “home” button, Busy Shapes features a customizable Guided Access. This feature also disables selected parts of the screen for safety and protection. SEAMLESS INTERACTION Busy Shapes’ seamless interactive game area never blocks or limits children, and lets them freely access shapes. The menu is also neatly hidden away. AUTOMATIC MEMORY Sometimes the best learning is a combination of cognitive exercise and physical play. Busy Shapes’ automatic memory saves a child’s place in any particular game, which makes the app an ideal complement to physical play and for shorter games. MULTIPLE LANGUAGE SUPPORT The app is now available in: English, French, Spanish, Portuguese, German, Italian, Greek, Dutch, Finnish, Norwegian, Swedish, Danish, Turkish, Russian, Korean, Indonesian, Malay, Vietnamese, Thai, Traditional Chinese and Simplified Chinese CONNECT WITH US!
