LinearSolver is an app that designed to solve systems of linear equations with n variables. You enter equations in the field, then choose solving method and press a button «Solve». Then program solves your linear system. There are two methods for solving: Gaussian elimination and Cramer's rule. For more intelligibility enable the «detailed solution».
eXpimal
This app provides advanced tools for creating truth tables, simplifying Boolean functions, and plotting logical schemes. It supports various methods for minimization and polynomial representation, with detailed results and comments.
- Truth table creation
- DNF, CNF, PDNF, PCNF calculation
- Zhegalkin polynomial generation
- Karnaugh map plotting
- Boolean function minimization
- Logical scheme plotting
- Ladder diagram creation

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.

Verdict
The clearest difference is review sentiment: eXpimal at 55% against LinearSolver's 0%. eXpimal also leads on update cadence (every 3 weeks vs every 39 months) and ratings volume (3 vs 1). LinearSolver's advantage is rating (3.0 vs 2.3) and price ($1.99 vs $2.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
LinearSolver costs $1.99 and eXpimal $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
LinearSolver holds the better App Store score, 3.0 against 2.3. Both are backed by a comparable volume of ratings — 1 and 3 respectively. Written reviews complicate that: 0% of LinearSolver's written reviews are positive against 55% of eXpimal's, so the app with the better star average is not the one people write more warmly about.
LinearSolver ships an update every 39 months, eXpimal every 3 weeks. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
