# Calc vs Dev Calc

The clearest difference is rating: Calc at 3.0 against Dev Calc's 2.0. Calc also leads on in-app purchases (none vs 1) and ads (none vs shown). Dev Calc's advantage is update cadence (every 2 months vs every 10 months) and review sentiment (60% vs 50%). On price, ratings volume, device support and iOS requirement there is nothing between them.

Both are free to download. Dev Calc sells 1 in-app purchase, starting at $1.99 per month. Calc asks for nothing beyond the download.

Calc holds the better App Store score, 3.0 against 2.0. Both are backed by a comparable volume of ratings — 2 and 2 respectively. Written reviews complicate that: 50% of Calc's written reviews are positive against 60% of Dev Calc's, so the app with the better star average is not the one people write more warmly about.

Calc ships an update every 10 months, Dev Calc every 2 months. The most recent releases landed on October 2, 2026 and October 7, 2026 respectively.
