Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Plaaan holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Simple Calendar・Schedule app has 2.5K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 79% of Simple Calendar・Schedule app's written reviews are positive against 0% of Plaaan's, so the app with the better star average is not the one people write more warmly about.
