# CalcMate vs Scientific Computer

The clearest difference is ads: Scientific Computer at none against CalcMate's shown. Scientific Computer also leads on iOS requirement (13.0 vs 16.0). CalcMate's advantage is ratings volume (96 vs 1). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. CalcMate sells 5 one-off in-app purchases and Scientific Computer sells 1 in-app purchase, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for CalcMate against 5.0 for Scientific Computer. That said, the two scores are not equally well evidenced: CalcMate has 96 ratings behind it against 1, so its average is the more settled of the two.

CalcMate ships an update fortnightly, Scientific Computer every 2 weeks. The most recent releases landed on September 21, 2026 and June 3, 2026 respectively.
