app includes all the words and context sentences necessary to play the demo
word packs.

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.
