Command-Line Calculator (CLCalculator) provides the most fluid interface, especially if you are performing chained calculations i.e. multiple calculations that rely on the results of previous calculations. By providing a command-line interface, CLCalculator allows you to easily enter and view the history of your calculations. You focus on your calculations instead of being intimidated by myriad of buttons on a traditional calculator interface! In addition to performing basic calculations, CLCalculator provides an array of features such as: - Assign and reuse variables - Complex numbers - Number bases i.e. binary, octal, hexadecimal - Constants e.g. e, pi - String manipulation - Matrices - Unit conversion: in-built and user-defined (create your own units!) - Functions: in-built and user-defined (create your own functions!) - Arithmetic functions e.g. fraction, square root, rounding off, ceiling, floor, logarithm - Algebra functions e.g. derivative, simplify symbolic expressions, solve linear equations - Bitwise functions e.g. bitwise and, not, or, left and right shift - Combinatorics functions e.g. Bell, Catalan, Stirling numbers - Geometry functions - Logical functions e.g. and, not, or, xor - Probability functions e.g. combinations, permutations, factorial - Relational functions - Set functions e.g. cartesian product, intersection, union - Statistics functions e.g. mean, median, mode, standard deviation, variance - Trigonometry functions e.g. sin, cos, tan, cot, sinh, acos - and much more! The app also comes with a comprehensive in-built help system with plenty of examples. CLCalculator is powered by math.js (https://mathjs.org/)

Verdict
The clearest difference is update cadence: Command at every 5 days against Calculator HD's every 6 months. Calculator HD's advantage is iOS requirement (9.0 vs 13.0). On price, ads, in-app purchases and device support there is nothing between them.
