Levy app for iPhone and iPad

Test your mental mind capabilities with Levy!

The Levenshtein distance between two words is defined as the minimum number of single-character edits (i.e. insertions, deletions or substitutions) required to change one word into the other.

For example, the words mitten and sitting have a Levenshtein distance of 3. The m would be substituted for an s, the e would be substituted for an i and a g would be inserted at the end.

It is named after Vladimir Levenshtein, who first considered this distance in 1965.

Your objective in Levy is to determine which of the three options is the specified number of edits away from word at the top of the screen before time runs out!
