## Description

**Ohms Law Calc.** is a comprehensive electrical engineering and circuit design toolkit for iPhone, iPad, and Mac. It includes 60 calculators with formulas and circuit diagrams, plus 16 converters for common electrical units.

Calculate voltage, current, resistance, power, voltage drop, wire size, transformer values, impedance, power factor, efficiency, energy storage, reactance, resonance, component sizing, voltage division, illumination, and more. Convert units such as volts, ohms, farads, henrys, kVA, webers, charge density, conductance, resistivity, and electrical power. Supports single-phase, three-phase, DC, series, parallel, star-to-delta, and delta-to-star calculations.

## Review summary

Users broadly praise the app for useful, time-saving Ohm's law and conversion calculations and the developer’s responsiveness. However, recurring issues with licensing/pay prompts, occasional crashes, and UI glitches hurt the experience. Some reviewers question calculation accuracy and find certain tasks less intuitive (e.g., parallel resistors) compared with web tools. Overall value is seen by many, but reliability and consistency need improvement.

### Pros

- Very useful for electricians and quick calculations
- Broad set of electrical conversions/calculations with a simple, easy-to-use UI
- Developer is responsive and actively improves the app based on feedback
- Time-saving for circuit/relay calculations
- Good value for money / affordable price

### Cons

- License/paywall issues after purchase: app remains locked, prompts to pay again, and poor support or responsiveness from the developer
- Stability issues: app frequently crashes or closes during use
- UI/UX problems on mobile: keyboard/input overlays obscure results and formulas on screen
- Possible inaccuracies in Ohm's Law expressions within the app (mislabeling or incorrect relationships)
- Some tasks (e.g., parallel resistor calculations) are not as intuitive and may be easier with web calculators
