# Nuten vs Calculus

The clearest difference is in-app purchases: Nuten at none against Calculus's 13. Nuten also leads on review sentiment (67% vs 33%) and update cadence (every 6 weeks vs every 16 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. Calculus sells 13 one-off in-app purchases. Nuten asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 3.6 for Nuten against 3.5 for Calculus. That said, the two scores are not equally well evidenced: Nuten has 51 ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 67% of Nuten's written reviews are positive against 33% of Calculus's.

Nuten ships an update every 6 weeks, Calculus every 16 months. The most recent releases landed on October 24, 2026 and September 27, 2026 respectively.
