ENGR*IT

146 calculators and engineering tools in one app—electrical, power, PCB, embedded, programmer, bitwise, financial, circuit visuals, sharing, and more.

ENGRIT is the ultimate calculator for everyone. Whether you need a powerful Standard or Scientific calculator, financial tools, engineering calculations, programmer functions, or bitwise operations, ENGRIT brings them together in one massive technical toolkit built for engineers, technicians, makers, students, and anyone who works with real-world calculations. Instead of jumping between separate apps, web pages, notes, and reference sheets, ENGRIT brings 146 calculators and engineering tools together in one focused workspace. CALCULATE ACROSS DISCIPLINES Work with electrical engineering, power, resistor and capacitor networks, PCB design, embedded systems and interfaces, Ohm’s Law, bitwise operations, programmer math, financial calculations, and standard/scientific math. ENGINEERING TOOLS THAT WORK TOGETHER ENGRIT is designed as more than a collection of isolated calculators. Calculated values can be copied, pasted, shared, or moved directly into another calculator. Use “Move to…” to send a result into another compatible tool and continue your work without re-entering the value. CIRCUIT VISUALIZATION Supported electrical calculations include integrated circuit diagrams that reflect the selected formula and calculated values. Zoom, pan, fit the diagram to the screen, and share the complete calculation artifact. BUILT FOR REAL ENGINEERING INPUT ENGRIT understands engineering-style values and units. Enter values such as kΩ, mA, µF, MHz, mil, mm, and inches using calculator-specific input controls designed for the type of value being entered. PCB AND EMBEDDED TOOLS PCB tools cover trace width and current, trace resistance and voltage drop, via current, microstrip and stripline, differential pairs, creepage and clearance, copper weight and thickness, AWG resistance, and wire voltage drop. Embedded tools include timers and prescalers, PWM, UART, SPI, I²C, CAN, ADC, DAC, quantization, sampling, and Nyquist calculations. POWER AND ELECTRICAL Work with DC and AC power, single-phase and three-phase systems, inductors, RLC circuits, voltage and current dividers, reactance, resonance, time constants, RMS/peak conversions, dB calculations, wavelength, Zener regulators, battery packs and runtime, and much more. PROGRAMMER + BITWISE Convert between DEC, HEX, OCT, and BIN, work with signed and unsigned values, choose common word sizes, and perform bitwise operations including AND, OR, XOR, NOT, shifts, rotates, set, clear, flip, and read bit operations. YOUR WORK, YOUR WAY ENGRIT includes calculation history, configurable swipe favorites, global calculator search, exact tool deep-linking, light and dark appearance support, sharing, and persistent last-calculated-value tools. FREE TO START Standard and Scientific calculators remain available without Pro. Start a free 7-day ENGRIT Pro trial to explore the complete toolkit.
