Why We Recommended It
Circuit Calculator is currently free on the App Store, dropping its original $0.99 price to zero. This essential productivity tool lets students, engineers, and hobbyists quickly build, simulate, and solve linear AC/DC circuits directly on their iPhone or iPad. Unlike many expensive circuit simulators that require steep learning curves, Circuit Calculator offers a streamlined drag-and-drop interface with real-time animations, support for rectangular and polar notation, and instant computation of voltages, currents, and power. Whether you're double-checking homework, verifying a design, or experimenting with Thévenin and Norton equivalents, this app handles it all with ease. It even includes pre-built example circuits and an interactive user guide to get you started fast. With iCloud sync across devices, export to PDF, and the ability to import circuits from others, Circuit Calculator is a versatile companion for any electronics workflow.

User Reviews
Can you also add the possibility for resistors to be read in voltage and ability to converting to resistance? Add batteries? Some circuits the resistors have voltages read as them we must find Vfb in the circuit aka high and low sides. Also I get it’s a calculator but I just built a circuit and didn’t get any option for calculation.
