Spel It Rite Pro App for iOS
'This is an enhanced version of the "Spel It Rite" game. The main objective is to select the correctly spelled words as fast as possible. For each wrong answer, a penalty of 5 seconds is added to the total time.
In this version, the size of the word corpus has been increased to more than 3000 words. In addition, apart from being able to review the list of misspelled words, the user can now also tap on them to see their definition and synonyms. New is also the possibility to hear the correct word pronunciations. Since the audio files are located on a web server, this feature requires internet connectivity (WiFi, 3G, Edge).'
This app costs $0.99
