Neuroo is a free flashcard application that allows you to learn vocabulary (or whatever else) throughout the day, at home or at work. Its aim is to be very straightforward and convenient to use, and to be able to be used everywhere (keeping your decks of flashcards and progress synchronized). A pop-up will appear regularly, asking if you remember this flashcard or not. For now, it has been developed only for Google Chrome, as an extension. Later on, iPhone, Android, and Window Mobile versions will be added, and will work all together along with the Google Chrome’s version. Screenshots.
