# Calculator Pro & Currency vs Ecthus

The clearest difference is rating: Calculator Pro & Currency at 4.6 against Ecthus's 4.0. Calculator Pro & Currency also leads on ratings volume (49 vs 3) and iOS requirement (12.4 vs 15.6). Ecthus's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Calculator Pro & Currency sells 2 one-off in-app purchases. Ecthus asks for nothing beyond the download.

Calculator Pro & Currency holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Calculator Pro & Currency has 49 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 75% of Calculator Pro & Currency's written reviews are positive against 100% of Ecthus's, so the app with the better star average is not the one people write more warmly about.

Calculator Pro & Currency ships an update monthly, Ecthus weekly. The most recent releases landed on October 26, 2026 and October 30, 2026 respectively.
