YouTellMe! does not rotate when you rotate your iPad. This is to make sure the Person opposite can always see the big Text.
If the Person opposite you ist typing, you can rotate the display with the Pasted Graphic button.

Now, this is actually the rotation if You are typing - but you got the message...

Adjust the text size of the white textfield with the Pasted Graphic 1 buttons.
The text size of the yellow textfiled can be adjusted with the
Pasted Graphic 2 buttons.

You can also use a pinch-gesture with two fingers in the yellow field to adjust the text size easily.

If the text gets too long to be displayed, the beginning will be deleted automatically.

YouTellMe is also helpful for people who cannot speak, for instance due to tracheostomy.
