This is exactly what I expected from this app. Simple and uncomplicated. I like that I can toggle right/wrong, text size, and score by half-points (paid version). Suggestions for improvement would be to allow the user to change the rounding of the grade (I would prefer to see whole number percentages). Also, there is a bug that only allows the user to enter one digit at a time in the score field. Then the app ejects you from the field and you have to click back in to type another digit.
