Statistics • Graphing • Scientific • Matrix calculator. 100% free. No ads. No “upgrade to unlock” functions. All equivalent functions of a TI 84 calculator, Casio calculator or HP calculator.\n\nPaying $100+ for a graphing calculator is just silly. Here’s our logic:\n1. We’ve built a beautiful, easy to use online digital calculator right there on your phone.\n2. The problem is, that you can’t use your phone on tests, so you’re stuck paying $100+ for your calculator.\n3. Not anymore!\n4. With our easy-to-use Test-Mode lockdown, you can now use ClassCalc on tests. Teachers can ask students to temporarily lock their own devices* out of all outside distractions such as instagram, calls and texts, keeping students focused in class, and preventing cheating on tests. Students can leave Test Mode whenever, and once they do, the teacher is notified.\n\n*Note: Teacher only has access to whether the student is in lockdown mode or not, and nothing else. The teachers will NOT be able to control their student’s device.\n\nTo get started, or to help your teacher get started, contact us at team@classcalc.com, or visit our tutorials at classcalc.com/tutorials.\n\nList of features:\n\nScientific Calculator:\n\nAlgebra – Advanced Statistics – Trigonometry – Calculus\nFeatures: Cos, pi, average, derivative, factorial, ln, log, median, mode, ncr (combinations), npr (permutations), percentage, roots, sin, standard deviation, tan, variance, GCD,  indefinite integral, modulus, sin inverse, convert decimal to fraction, sin, cos, tangent, trig inverse, exponents\n\nGraphing and Statistics Calculator: \n\nGraphing – Algebra  – Advanced Statistics  – Trigonometry – Calculus (& Precalculus)\nFeatures: Plot functions, anova, binomial distribution, cdf, chi square test, derivative, histogram, linear regression, log, normal distribution, Poisson distribution, polynomials, regressions, tables, min, max, intercepts, intersections, parametric equations, polar coordinates, t test, z test, mean, median, mode, range, combinations (nCr), permutations (nPr), factorial, standard deviation, variance, sort, linear regression, statistics calc (abscissae), function, polynomial regression, exponential regression, sinusoidal regression, logarithmic regression, random number, one variable statistics (1varstats), two variable statistics (2varstats)t distribution, geometric distribution, chi square distribution, Cumulative distribution function, Probability density function, histograms, box plots, qq plots (normal probability plot), hypothesis testing, statistical testing, ztest, proportion testing, interval testing, hypothesis interval, t interval, derivatives, integrals, statistics tools, find vertices of a graph, exponential equations, quadratic functions, linear functions, linear equations, inverse functions, asymptotes, radical functions, roots, conics, circle, ellipses, parabolas, hyperbolas, trig functions, absolute value functions, exponential growth, exponential decay, graphical representation (graphic calculator), graph amplitudes, \n\nMatrix Calculator (matrixcalc): \n\nLinear Algebra – Algebra II\nFeatures: Determinant, matrices, inverse matrix, matrix multiplication, reduced row echelon form, row echelon form, system of equations, transpose matrix, adding matrices\n\nContact: Info@ClassCalc.com","facts":{"developer_id":1314362548,"developer_url":null,"first_released":"2018-03-08T01:21:58Z","support_url":"http://classcalc.com/tutorials","privacy_url":"https://app.termly.io/document/privacy-policy/a419c907-9462-44df-a2a3-4676cd2feb29","website_url":null,"app_version":"1.12.26","release_notes":"Bug fixes and minor improvements","rating_current_version":4.9136,"rating_count_current_version":1713,"star_counts":[3,0,13,110,1574],"genres":["Education","Utilities"],"languages":["EN"],"content_advisories":null,"device_families":["iphone","ipad","ipod"],"made_for_iphone_duo":false,"chart":null},"freshness":{"apple_read_at":"2026-11-14T17:01:13.446Z","catalog_read_at":"2026-10-29T16:22:12.586Z","reviews_checked_at":null,"summary_written_at":"2026-10-25T02:11:12.775Z","placed_at":"2026-10-25T01:53:12.749Z","scored_at":"2026-11-14T15:21:12.738Z"},"editorial":{"one_liner":"Free scientific, graphing, statistics and matrix calculator with a Test Mode lockdown for use on tests.","what_is":"ClassCalc Graphing Calculator is a free education app listed as a scientific, graphing, statistics and matrix calculator.
