Audio Anki

Audio Anki is a learning application designed for those who want to optimize their time. It is similar to Ankidroid but, instead of writing flashcards, you record short audios of subjects you have to remember. Every time an audio is listened, it goes to the end of the queue. You can listen to your records while driving or doing house working.
Ankidroid is a great app for learning languages and other subjects as well. But, sometimes is easier to review flashcards by listening to them while doing other daily tasks.
Audio Anki is a must have complement for Ankidroid.
