Stackz is a flashcard software that uses a unique visual interface to help users keep track of their progress in learning a large amount of vocabulary. The software graphically displays cards according to mastery level and date of last practice, allowing for efficient and effective review.

With this system, you can easily distinguish easy and difficult cards while seeing which ones need to be refreshed because they haven't been reviewed for a while. Stackz is compatible with any other Unicode language of the Windows operating system as well. Furthermore, the constantly growing online wordlist archive currently contains over 200 wordlists for Japanese, Chinese, Korean, and Thai.
If you want to take the Stackz flashcard system on the go, there's also a Pocket PC version available. This version allows for seamless synchronization of the learning status between platforms, and you can directly download wordlist files to the Pocket PC. Overall, if you're looking for an intuitive and convenient way to keep track of your language learning progress, be sure to check out Stackz.
