# DataAnalysis vs QuickNotes X

The clearest difference is in-app purchases: DataAnalysis at none against QuickNotes X's 11. DataAnalysis also leads on review sentiment (64% vs 38%) and iOS requirement (14.0 vs 16.0). QuickNotes X's advantage is ratings volume (3.8K vs 106) and rating (4.3 vs 4.1). On price, update cadence and ads there is nothing between them.

Both are free to download. QuickNotes X sells 11 in-app purchases, starting at $0.99 per 3 months. DataAnalysis asks for nothing beyond the download.

QuickNotes X holds the better App Store score, 4.3 against 4.1. That said, the two scores are not equally well evidenced: QuickNotes X has 3.8K ratings behind it against 106, so its average is the more settled of the two. Written reviews complicate that: 64% of DataAnalysis's written reviews are positive against 38% of QuickNotes X's, so the app with the better star average is not the one people write more warmly about.

DataAnalysis ships an update every 2 months, QuickNotes X every 5 weeks. The most recent releases landed on September 22, 2026 and October 4, 2026 respectively.
