Welcome to the Professor Ninja website!
Professor Ninja can help you learn a foreign language. Our apps offer a unique method for vocabulary learning, based on practice by repetition and tests. If you've ever used flashcards for foreign language learning, you will definitely like the Professor Ninja concept. But our apps offer much more than traditional flashcards do, and they are fun to use.
Using Professor Ninja, you will master your basic English / Spanish / Chinese (Mandarin) / Japanese / German / Hebrew / French / Dutch / Danish / Finnish vocabulary in just a few days.
At present, the Professor Ninja product line includes 10 iPhone/iPad apps for vocabulary learning. However, we are working on some new products, so visit this site regularly to find out about what is new.
