app includes all the words and context sentences necessary to play the demo
Because the audio files take up valuable storage space on your device, you will need to download the files for each word pack.
If some of the words are already included in another word pack, then these won't be downloaded again.
You can always delete files and download again as and when you need them, at no extra charge (ie. once you've paid for the word pack you can download and delete the files as many times as you want). This allows you to keep the storage footprint of our app to a minimum, if available space is important to you.
