## Description

Engineering Calculator with unit converter, function graphs and 100+ formulas for students, engineers and electricians. Convert units in seconds, plot graphs, solve equations, calculate Ohm&#39;s law, voltage drop, cable size and beam loads. Fully offline, no account, no data collection.<br><br>WHO IT&#39;S FOR:<br>- Students and teachers: scientific calculator, equation solving, graphs and a formula library for study and exams.<br>- Engineers and technicians: unit converter, matrices, vectors, complex numbers and mechanics helpers for daily work.<br>- Electricians: Ohm&#39;s law, voltage drop, cable sizing, three-phase power and resistor color codes.<br>- Builders and construction workers: concrete, tile, paint, slope, stairs and brick estimates on site.<br>- Mechanics and programmers: torque, gears, springs, plus BIN/OCT/DEC/HEX and bit operations.<br><br>EngiCalc includes:<br><br>- Basic and engineering calculator modes with ANS, memory, constants, powers, roots, logarithms, factorials, percentages, and degree/radian trigonometry.<br>- Programmer calculator with BIN/OCT/DEC/HEX, signed and unsigned values, 8/16/32/64-bit modes, AND/OR/XOR/NOT, shifts, rotates, ASCII/Unicode, Unix time, Base64, and URL tools.<br>- RPN, matrix, vector, complex number, and equation-solving workflows for technical math.<br>- Unit converter for length, area, volume, mass, temperature, pressure, energy, power, speed, acceleration, force, density, torque, flow, angle, electrical units, time, frequency, data, and fuel consumption.<br>- Electronics helpers for Ohm&#39;s law, voltage drop, voltage divider, series/parallel resistance, current divider, three-phase power, cable sizing, LED resistors, RC/RL time constants, decibels, resistor color code, and RLC circuits.<br>- Construction, geometry, mechanics, physics, and chemistry helpers for concrete, tile, paint, plaster, slope, stairs, bricks, torque, gears, springs, beams, friction, power, work, kinetic energy, momentum, ideal gas, concentration, mass fraction, and pH.<br>- Graphing with zoom, pan, multiple functions, value analysis, roots, min/max samples, derivative and integral estimates, intersections, SVG export, and project saving.<br>- Formula library, favorites, custom reusable formulas with variables, and custom linear units.<br>- Local history, searchable records, notes, tags, projects, templates, CSV/PDF/text exports, and local encrypted backup/restore.<br>- Themes, AMOLED mode, high contrast, haptics, precision settings, language selection, and offline-first privacy.<br><br>OFFLINE &amp; PRIVACY:<br>Everything works fully offline — on site, in the field or in flight. No account, no registration and no data collection: your calculations stay on your device.<br><br>PRO:<br>Optional Pro upgrades through Google Play unlock unlimited local history and projects, custom workflow features, advanced graph presets, exports, backup/restore, and additional customization. The free version remains a complete calculator and unit converter.<br><br>Important: Results are estimates and helper calculations. Critical engineering, electrical, construction, chemical, medical, or safety-related work must be verified with certified tools, current standards, manufacturer specifications, and qualified professionals.
