Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Notion Calendar holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 2.8K and 7.7K respectively. Written reviews complicate that: 62% of Obsidian's written reviews are positive against 39% of Notion Calendar's, so the app with the better star average is not the one people write more warmly about.
