# Concepts vs ChartStudio

The clearest difference is rating: Concepts at 4.7 against ChartStudio's 2.7. Concepts also leads on review sentiment (77% vs 44%) and ratings volume (26K vs 3). ChartStudio's advantage is device support (5 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Concepts sells 13 in-app purchases, starting at $4.99 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.

Concepts holds the better App Store score, 4.7 against 2.7. That said, the two scores are not equally well evidenced: Concepts has 26K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 77% of Concepts's written reviews are positive against 44% of ChartStudio's.

Concepts ships an update fortnightly, ChartStudio monthly. The most recent releases landed on September 25, 2026 and September 15, 2026 respectively.
