# TnECHO vs AnthroCalc

The clearest difference is review sentiment: TnECHO at 80% against AnthroCalc's 46%. TnECHO also leads on iOS requirement (7.1 vs 16.4). AnthroCalc's advantage is update cadence (weekly vs every 3 months) and rating (3.5 vs 3.2). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

AnthroCalc holds the better App Store score, 3.5 against 3.2. Both are backed by a comparable volume of ratings — 5 and 2 respectively. Written reviews complicate that: 80% of TnECHO's written reviews are positive against 46% of AnthroCalc's, so the app with the better star average is not the one people write more warmly about.

TnECHO ships an update every 3 months, AnthroCalc weekly. The most recent releases landed on October 23, 2026 and October 25, 2026 respectively.
