# Scientific++ vs Phase Calc

The clearest difference is rating: Phase Calc at 5.0 against Scientific++'s 4.5. Phase Calc also leads on update cadence (every 6 weeks vs every 6 months) and review sentiment (100% vs 89%). Scientific++'s advantage is ratings volume (61 vs 4) and price ($0.99 vs $1.99). On ads, in-app purchases and device support there is nothing between them.

Scientific++ costs $0.99 and Phase Calc $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Phase Calc 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 4, so its average is the more settled of the two. Written reviews point the same way: 89% of Scientific++'s written reviews are positive against 100% of Phase Calc's.

Scientific++ ships an update every 6 months, Phase Calc every 6 weeks. The most recent releases landed on September 24, 2026 and August 1, 2026 respectively.
