This is a free lite version which has a LIMIT of 4 decks and 6 cards per deck. The paid version does not have this restriction.

Flashcards Deluxe is an easy to use, yet powerful flashcard app which you can use to study just about anything you want. I use this app for my own Chinese studies, and am constantly improving it to make it better for myself and others.

You can create flashcards either on your computer or directly within the app. If you don't want to make your own, you can browse and download flashcards from the app's Shared Library.

Creating cards on your computer is an easy process of making a two column list of questions and answers in a text editor or spreadsheet, copy/pasting your list into our website, and then downloading it to your device. You can also transfer flashcards using Dropbox, Google Docs or even your own web server.
