# Fast Chart vs ChartStudio

The clearest difference is rating: Fast Chart at 4.5 against ChartStudio's 2.7. Fast Chart also leads on review sentiment (80% vs 44%) and ratings volume (89 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fast Chart sells 3 in-app purchases, starting at $2.99 per month and ChartStudio sells 5 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Fast Chart holds the better App Store score, 4.5 against 2.7. That said, the two scores are not equally well evidenced: Fast Chart has 89 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 80% of Fast Chart's written reviews are positive against 44% of ChartStudio's.

Fast Chart ships an update every 10 days, ChartStudio monthly. The most recent releases landed on September 23, 2026 and September 15, 2026 respectively.
