RPN's advantage is price ($2.99 vs $7.99) and rating (4.8 vs 4.6). On ads, in-app purchases, monetization model and device support there is nothing between them.

RPN costs $2.99 and RE.minder PRO+ $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.

RPN holds the better App Store score, 4.8 against 4.6.

Written reviews complicate that: 68% of RPN's written reviews are positive against 87% of RE.minder PRO+'s, so the app with the better star average is not the one people write more warmly about.
