Scientific Calculator-Arivon is a dense, professional-grade scientific
calculator that works completely offline — no ads, no account, no internet
required to calculate.

FULL SCIENTIFIC KEYPAD
• Natural expression entry with correct operator precedence and implicit
multiplication
• Powers, roots, trigonometry & inverse trigonometry, logarithms, factorial
and percentages
• DEG/RAD modes, Ans, permutations, combinations and GCD
• Editable cursor, memory, previous-answer recall, engineering notation and
DMS output
• Live result preview and in-session calculation history

GRAPHING
• Interactive function graphing with pinch-to-zoom
• Quadratic equation solver, including complex roots

OFFLINE CAS (COMPUTER ALGEBRA SYSTEM)
• Exact linear, polynomial, radical, logarithmic and parameterized equation
solving
• Simultaneous symbolic equation systems with multiple variables
• Symbolic simplify, expand, factor, differentiate and integrate
• Limits, Taylor/Maclaurin series and Laplace/inverse-Laplace transforms
• All CAS work runs in a background thread, so it never freezes the keypad

ENGINEERING SUITE
• Statistics: mean, median, sample standard deviation
• Matrix and 3D vector tools
• Ohm's law and electrical power calculations
• Unit converter: length, mass and temperature

MEDICAL / CLINICAL SUITE
• BMI, BSA, renal-function and infusion-rate arithmetic
• Formula-based support only — always verify against approved clinical
references. Not a substitute for professional medical judgement.

WHY THIS CALCULATOR
• 100% offline — every calculation happens on your device
• No account, no login, no tracking of what you calculate
• Responsive Material 3 interface with light and dark themes
• Dense, reference-calculator-style keypad with SHIFT/ALPHA secondary
functions for power users

Medical calculators provide formula-based arithmetic support only. Inputs,
units, formula suitability, and results must be independently verified using
approved clinical references. This app must not be used alone for
diagnosis, prescribing, or treatment decisions.
