The most functional math logic calculator. This application has the functions as follows: - creating truth tables; - finding DNF, CNF, PDNF and PCNF; - finding Zhegalkin polynomial (Undetermined coefficients method and Pascal's triangle method); - making a Karnaugh map; - minimizing Boolean function with equivalence conversion (both briefly and in details); - minimize partially defined functions; - belonging to the Post classes; - plotting logical schemes (both IEC and ANSI schemes); - plotting ladder diagram; - minimizing functions using McCluskey method. Boolean functions may be displayed as multiple characters. Unary operation "negation" may be displayed either as a single character or in the form of an overline. Maximum number of variables in the function is limited by 6. Maximum number of function-embedded negations is limited by 5. Maximum number of characters in the function is limited by 64. Karnaugh maps, PCNF and PDNF functions, Zhegalkin polynomial and the McCluskey method only may be used for operating a value vector. The modulus of vector shall contain 4, 8, 16, 32, or 64 characters. The values of 0 and 1 may be used in this function but it will be subject to simplification only. The implication is inadmissible for plotting a logical scheme. No ads pop up. This application demonstrates intuitively understandable and trouble-free operations. All results are shown in details along with comments.
Equation Solver & Simplifier
This app helps you solve algebraic equations by showing every step of the simplification process. It can find the value of 'x' or the zeros of a function using a numeric algorithm after simplifying your input.
- Algebraic equation solving
- Step-by-step simplification
- Numeric algorithm for solutions
- History function
- Decimal input support
- Constants and variables support

Verdict
The clearest difference is price: Equation Solver & Simplifier at Free against eXpimal's $2.99. Equation Solver & Simplifier also leads on rating (4.4 vs 2.3) and review sentiment (75% vs 55%). eXpimal's advantage is in-app purchases (none vs 8) and iOS requirement (12.1 vs 15.0). On update cadence, ads and device support there is nothing between them.
