Really badly designed UI

On the iPad: Crashes at the end of every test. Crashes every time you tap the Results section, therefore you can never see your results.
On the iPhone: No crashes but badly rendered UI in portrait orientation where the text runs over the controls in the Settings section and text runs over other text on the Results page.
