Word Carrot is LearnAhead’s first iPhone app published on the app store on 5 January 2012.  It’s a free app with 90 words and will soon be updated to enable learners to buy more words through in-app purchase.  We will then release a US English version, and an iPad version, though the current version also works on iPad.  In the longer term we hope to publish for Android and in other languages.  The accompanying website has articles and free worksheets that teachers can use for teaching the word sets featured in the apps.
