# Calc vs Calculator%.

The clearest difference is rating: Calculator%. at 4.4 against Calc's 3.9. Calculator%. also leads on in-app purchases (none vs 2) and ratings volume (4.2K vs 28). Calc's advantage is ads (none vs shown) and review sentiment (81% vs 61%). On price, update cadence and device support there is nothing between them.

Both are free to download. Calc sells 2 in-app purchases, starting at $0.99 per month. Calculator%. asks for nothing beyond the download.

Calculator%. holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Calculator%. has 4.2K ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 81% of Calc's written reviews are positive against 61% of Calculator%.'s, so the app with the better star average is not the one people write more warmly about.

Calc ships an update every 2 months, Calculator%. every 3 months. The most recent releases landed on September 20, 2026 and September 23, 2026 respectively.
