Scientific Calculator: SciCalc

A serious four-line scientific calculator for students and engineers, with a textbook-style display and exact answers. Intended for use with the TI-36X Pro: the keys, menus and screens follow that calculator's layout, so what you practise on your phone is what you'll press in class and on exam day. STUDYING FOR THE FE OR PE? Work through practice problems on the same layout you'll use on exam day, with the same keys and the same menus. WHAT IT DOES • Textbook display: fractions, roots, powers, integrals and derivatives look the way they do in your book • Exact answers: fractions, √ and π results, with one key to switch to decimals • History you can scroll: touch an earlier entry or answer to use it again • Solvers: quadratic and cubic equations, 2×2 and 3×3 linear systems, and a numeric equation solver • Statistics: one- and two-variable stats, six kinds of regression, and normal, binomial and Poisson distributions • Matrices and vectors, complex numbers (a+bi and polar), and HEX, BIN and OCT with logic operations • Function tables, stored operations, physical constants and unit conversions • Light and dark themes, adjustable text size and screen height, and a light haptic tick on every key • Works completely offline, with no account and no sign-up SCICALC36 PRO An optional upgrade, monthly, yearly or one-time (Lifetime).
