NumberCatcher app for iPhone and iPad

Number Catcher is a fun, fast-paced game that lets you play with numbers, while training basic concepts of number and arithmetic:
- Basic calculation skills : addition and subtraction
- Number formats : concrete sets, digits and number words
- The base 10 principle and the logic of multi-digit number

Number Catcher is primarily designed for children aged 5 to 10 but its higher levels can be fun for adults too!

Children who are making their first steps with numbers will learn the basic concepts of number and arithmetic. Older children, who are already familiar with numbers, will build their fluency in arithmetic. This game is especially designed to address mathematical learning disabilities (dyscalculia), by strengthening the brain circuits for representing and manipulating numbers.

This game is available in French and in English.
