Great when it works

I found this app to be extremely useful in learning a new language. The constant refreshing of vocabulary and verb forms has been a lifesaver for me. However, with two generations of iPhones I have continued to have problems with this app freezing up. The only way Ive been able to get the problem to go away, at least temporarily,is to delete and reinstall the app. Nevertheless, I highly recommend the app for anyone working on a language.
