# Logarithms vs Calcu

The clearest difference is rating: Calcu at 5.0 against Logarithms's 3.2. Calcu also leads on in-app purchases (none vs 3) and update cadence (every 3 days vs every 5 months). Logarithms's advantage is ratings volume (18 vs 1) and iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. Logarithms sells 3 one-off in-app purchases. Calcu asks for nothing beyond the download.

Calcu holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: Logarithms has 18 ratings behind it against 1, so its average is the more settled of the two.

Logarithms ships an update every 5 months, Calcu every 3 days. The most recent releases landed on September 10, 2026 and June 8, 2026 respectively.
