Mail Folders costs $3.99 and Keep Screen On $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Keep Screen On holds the better App Store score, 2.0 against 1.5.

Written reviews complicate that: 52% of Mail Folders's written reviews are positive against 40% of Keep Screen On's, so the app with the better star average is not the one people write more warmly about.
