Your digital electrical toolbox: calculate, plan, log meter readings and keep useful results organised across your Apple devices.

App Store Description

WattGuru turns your iPhone, iPad and Mac into a practical toolbox for electricity and energy. Calculate values, document meter readings and save calculation cases clearly – without a WattGuru account, advertising or tracking. ELECTRICAL TOOLS - Ohm's law from any two known values - Power and current for DC, single-phase AC and three-phase AC - Cable cross-section, voltage drop and maximum cable length - Energy, runtime, battery charging and consumption costs - Series and parallel resistor networks plus voltage dividers - Conversion of electrical units METERS AND COSTS Record household, sub, appliance, generation and storage meters. Log standard and off-peak readings, follow consumption and costs in charts, and exchange your own data using CSV when needed. PROJECTS AND REFERENCE Save calculator results together with inputs and assumptions in projects. The built-in reference explains voltage, current, power, energy, cables, protective measures and safe measurement in clear language. PRIVATE AND AVAILABLE ACROSS DEVICES Your data stays on your device by default. Optional iCloud sync keeps meters, tariffs and projects in step across your own Apple devices. cgNetsphere does not receive this content. WattGuru includes no advertising, tracking or analytics services. WattGuru is a calculation, planning and documentation aid. Work on electrical installations must be carried out by qualified people. Applicable standards, protective measures and manufacturer instructions always take precedence.
