# Charts vs Schema

The clearest difference is rating: Charts at 5.0 against Schema's 4.3. Charts also leads on review sentiment (100% vs 62%) and in-app purchases (none vs 4). Schema's advantage is update cadence (every 2 days vs every 6 months) and ratings volume (13 vs 2). On price and ads there is nothing between them.

Both are free to download. Schema sells 4 in-app purchases, starting at $9.99 per month. Charts asks for nothing beyond the download.

Charts holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Schema has 13 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of Charts's written reviews are positive against 62% of Schema's.

Charts ships an update every 6 months, Schema every 2 days. The most recent releases landed on October 5, 2026 and September 28, 2026 respectively.
