# AddCalc Freedom vs Dev Calc

The clearest difference is rating: AddCalc Freedom at 3.5 against Dev Calc's 2.0. AddCalc Freedom also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Dev Calc's advantage is iOS requirement (13.0 vs 15.6). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. AddCalc Freedom sells 1 one-off in-app purchase and Dev Calc sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

AddCalc Freedom holds the better App Store score, 3.5 against 2.0. Both are backed by a comparable volume of ratings — 4 and 2 respectively. Written reviews complicate that: 53% of AddCalc Freedom'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.

AddCalc Freedom ships an update every 6 weeks, Dev Calc every 2 months. The most recent releases landed on October 3, 2026 and October 7, 2026 respectively.
