# Art of Stat vs PixelMath

The clearest difference is monetization model: Art of Stat at free against PixelMath's free with in-app purchases. Art of Stat also leads on ratings volume (21 vs 1) and iOS requirement (15.1 vs 17.6). PixelMath's advantage is rating (5.0 vs 4.7) and update cadence (monthly vs every 3 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Art of Stat sells 5 one-off in-app purchases and PixelMath sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PixelMath holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Art of Stat has 21 ratings behind it against 1, so its average is the more settled of the two.

Art of Stat ships an update every 3 months, PixelMath monthly. The most recent releases landed on October 24, 2026 and October 17, 2026 respectively.
