# Expressions Calculator vs Scientific++

The clearest difference is price: Expressions Calculator at Free against Scientific++'s $0.99. Expressions Calculator also leads on rating (5.0 vs 4.5) and update cadence (monthly vs every 6 months). Scientific++'s advantage is ratings volume (61 vs 5) and review sentiment (89% vs 78%). On ads and in-app purchases there is nothing between them.

Expressions Calculator is free to download; Scientific++ costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Expressions Calculator holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Scientific++ has 61 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 78% of Expressions Calculator's written reviews are positive against 89% of Scientific++'s, so the app with the better star average is not the one people write more warmly about.

Expressions Calculator ships an update monthly, Scientific++ every 6 months. Both last shipped on October 23, 2026.
