More than 2000 German words in 57 categories including professions, food, or verbs. Select a category, and set of cards appears. Flip cards by tapping them β now try to find the pairs. Once you find a pair, MetaTwist will speak the word. Once you have found all the pairs, all cards are shown again with the appropriate applause. You can now repeat the words by tapping them. You can select the number of cards (4, 6, 12, or 24 cards). Tapping the β=β button repeats the same set of cards, so you can play again. By default, the words are spoken using the built-in iOS voice. With an inApp purchase you can buy additional voices (man/woman and boy/girl) from Acapela. To unlock these functions tap the edit key in the lower left corner and tap the numbers in the passcode in order from smallest to largest. Then tap the voice settings button to go to our voice store. The association of images, text and sound helps with learning to speak and to read. Even young children, that cannot read yet, are motivated by the images. The MetaTwist images are part of the METACOM symbol system and are known for their clarity and high quality graphics. The categories and words are based on the content of our MetaTalk app. MetaTwist helps MetaTalk users to explore the words in each category while playing. But MetaTwist goes beyond MetaTalk, it is an app for all users!
