Not really useful, requires portrait orientation
I really don’t see how anyone would become a more skilled keyboarder by tying asdfgjkkl;’, then qwertyuiop[], and then the bottom row, over and over.
The app will only display in portrait orientation. If your iPad is mounted with an external keyboard in the landscape orientation, such as you have with the Apple Magic Keyboard or the Logitech keyboard + case combination, this app is even more useless, since the app’s text and graphics will be sideways.
