# Calculator + vs Scientific++

The clearest difference is price: Calculator + at Free against Scientific++'s $0.99. Calculator + also leads on update cadence (every 4 days vs every 6 months) and ratings volume (10K vs 61). Scientific++'s advantage is in-app purchases (none vs 12) and ads (none vs shown). On rating, review sentiment, monetization model and device support there is nothing between them.

Calculator + is free to download; Scientific++ costs $0.99 up front. Calculator + sells 12 in-app purchases, starting at $4.99 per month. Scientific++ asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for Calculator + against 4.5 for Scientific++. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 61, so its average is the more settled of the two. Written reviews are what separate them: 85% of Calculator +'s written reviews are positive against 89% of Scientific++'s.

Calculator + ships an update every 4 days, Scientific++ every 6 months. The most recent releases landed on September 26, 2026 and September 24, 2026 respectively.
