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/)

RapidRoller is a dice and match-management tool designed for play in games such as Warhammer 40,000. Batch hit, wound, and save rolls to resolve complex dice quickly, and keep round, turn, CP, and VP together on one screen during a game. MAIN FEATURES • Attack Sequence — Enter unit stats to process hit → wound → save in one flow — Lethal Hits, rerolls, Sustained Hits, Anti-keyword, and more where supported in the app — View statistics such as expected values and success rates • Presets — Save and load frequently used unit setups • Quick Roll — General-purpose rolling: set dice count and sides and see results instantly — A good fit for charge rolls, random attack counts, damage rolls, and similar uses • Battle Management — One screen for round, turn, CP, VP, and VP history during a match — Review how the match progressed afterward • Results & history — Roll history and battle history — Export to JSON where supported • Settings — Adjust dice reveal timing — English / Japanese UI (switchable) NOTICE — Future updates The app currently targets 10th Edition rules. After full 11th Edition support, some features are planned to move to a subscription; core dice rolling and battle management will remain free. Features that may become subscription-only: • Selected advanced attack-sequence settings • Some statistics displays • Higher limits on history and preset storage, etc. DISCLAIMER RapidRoller is an unofficial fan-made tool and is not affiliated with or endorsed by Games Workshop or other rights holders.
