The 'I know it!' Button

Internally Memorize Words has a database of words with each word having the potential to become an English, Spanish, or Spanish Audio flashcard. During the lesson phase an enabled word is selected at random but biased towards words that are most frequently used. Select the right arrow, and you've created a flashcard; select 'I know it!', this word is disabled and another enabled word is selected.

If you go into the Dictionary and tap one of the three 'Add Card' buttons, you've created a flashcard from that word, and it will appear in the lesson without an 'I know it!' button because you've committed to learning it.

For the most part, stick to Settings > 'Enable Words' if you're building a word list. Use the Dictionary > 'Add Card' if you need learn a specific word. Hopefully this clears up any confusion.

Turning off Sound Effects

The Settings > 'Sound Effects' switch will re-enable if the application is restarted. This was a design choice to avoid confusion, but we can permanently store this value and post a warning dialog upon restart if that will help instead.

BTW, Thank you for the reviews on iTunes. Your support is vital to helping us create a better application.
